Additional Resources Addition and Subtraction Strategies Basic Multiplication and Division Strategies Four Corners and Rhombus Math Graphic Organizer Depth of Knowledge Levels/ Cognitive Complexity of Mathematics Items Planning INTRODUCTION TO PACING AND SEQUENCING- GRADE 5 INSTRUCTION: ALGORITHMS AND FORMULAS: All instruction must be standards-based. The textbook is a resource and textbook lessons must be carefully chosen and aligned with the standards targeted for instruction. It is critical that the Pacing and Sequencing Chart and the FSA Test Item Specifications are used for planning and implementing lessons. The entire Pacing and Sequencing Chart should be previewed in order to begin with the end in mind and understand how the mathematical concepts grow throughout the year. The standard algorithm for multiplication of whole numbers is introduced. The intent is that students will build on the knowledge about multiplication acquired in previous grades, especially 4th grade. This is not just a “rule” to be followed. Students must be encouraged to understand why it works. The standard algorithm for division is NOT to be introduced. Students are expected to solve division problems using strategies based on place value and properties. This algorithm is in the 6th grade standards. Operations with decimals are to be performed using strategies based on place value and properties with the ability to relate these strategies to written form. The standard algorithms for operations with decimals are introduced in 6th grade. The formula for volume of rectangular prisms is introduced in 5th grade. The intent is that students understand why this formula works, not just memorize and use it. It is not listed on the FSA Mathematics Reference Sheet nor will it be given with problems on FSA since it is a part of the standards. CONNECTIONS BETWEEN THE DOMAINS: Standards are not meant to be taught in isolation. Each standard supports other standards and will continue to be developed throughout the year. PROBLEM-SOLVING: Emphasis should be on engaging students in deeper levels of thinking and analyzing. Students must have many opportunities to explore the content of the standards through real-world problem-solving tasks. Mathematical discourse must be an integral part of instruction. MEASUREMENT: Hands-on opportunities for students to be engaged in measurement are critical. Hands-on measurement tasks may be taught within the science and social studies curricula. VOCABULARY: Correct mathematical vocabulary MUST be used. For example, students are expected to use terms such as addend, sum, factor, product, and so on. POST-FSA IDEAS: Students should continue to work on critical areas within the grade level standards. Project-based lessons and activities are encouraged. Possible resources to use are: AIMS Solve It!

FIRST NINE WEEKS Mathematics Florida Standards (MAFS) MAFS.5.NBT.2.5: Fluently multiply multi-digit whole numbers using the standard algorithm. MAFS.5.NBT.2.6: Find whole-number quotients of whole numbers with up to four-digit dividends and two-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models. Explanation and Examples* Fluency involves accuracy (correct answer), efficiency (a reasonable amount of steps), and flexibility (using strategies that demonstrate number sense). This standard builds upon students’ work with multiplying in third and fourth grades where they used various strategies to multiply. Students can continue to use these strategies as long as they are efficient, but must also understand and be able to use the standard algorithm. This standard extends students’ prior experiences with using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division to solve division problems. It also extends division to include 2-digit divisors from 4th grade. The standard algorithm is not taught until sixth grade. MAFS.5.NBT.1.1: In this standard, students must reason about the magnitude of numbers. Teachers should provide opportunities for students to Recognize that in a multi-digit number, a digit in one practice the concept that the value of the place is ten times as much as the place to its right and 1 the value of the place to the 10 place represents 10 times as much as it represents in left. This standard extends the understanding to the relationship of decimal fractions. Students must be able to explain the 1 the place to its right and of what it represents in 1 10 relationship between the two fives in 455.721 (5 is of 50). 10 the place to its left. Students may say, “I can show that the 5 to the left is 10 times larger than the five to the right.” Student’s response should reflect an understanding of how a digit’s position affects its value.

Pacing and Sequencing Chart Fifth Grade Mathematics Florida Standards 2015 - 2016 This standard includes multiplying by multiples of 10 and powers of 10, including 102 which is10 x 10 =100, and 103 which is Explain patterns in the number of zeros of the product 10 x 10 x 10 =1,000. Students should have experiences working with connecting the pattern of the number of zeros in the product when you multiply by powers of 10. when multiplying a number by powers of 10, and explain patterns in the placement of the decimal point Example: when a decimal is multiplied or divided by a power of What is the value of the missing exponent in the expression 523 ÷10□ = 52.3? 10. Use whole-number exponents to denote powers of Solution: 1 10. MAFS.5.NBT.1.3: Examples: 1 1 1 Read, write, and compare decimals to thousandths. a) A number in expanded form is shown. 3 × 1 + 2 × ( ) + 6 × ( )+5×( ) 10 1000 100 a. Read and write decimals to thousandths using What is the number in decimal form? 3.265 base-ten numerals, number names, and expanded form, e.g., 347.392 = 3 100 + 4 10 + 7 1 + 3 b) Compare 0.207 to 0.26: MAFS.5.NBT.1.2: ( 1 1 1 )+9( )+2( ). 10 100 1000 b. Compare two decimals to thousandths based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons. A student might think, “Both numbers have 2 tenths so I need to compare the hundredths. The second number has 6 hundredths and the first number has no hundredths, so the second number must be larger.” Another student might think while writing fractions, “I know 0.207 is 207 thousandths (and may write hundredths (and may write 207 ). 0.26 is 26 1000 26 260 ) but I can also think of it as 260 thousandths ( ). So, 260 thousandths is greater than 1000 100 207 thousandths.” MAFS.5.NBT.1.4: Use place value understanding to round decimals to any place. MAFS.5.NBT.2.7: Add, subtract, multiply, and divide decimals to hundredths, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used. Students should go beyond simply applying an algorithm or procedure for rounding. Example: Round 14.235 to the nearest tenth. Students recognize that the possible answer must be in tenths thus, it is either 14.2 or 14.3. They then identify that 14.235 is closer to 14.2 (14.20) than to 14.3 (14.30). 14.2 14.3 This standard builds on the work from fourth grade where students are introduced to decimals and compare them. In fifth grade, students begin adding, subtracting, multiplying and dividing decimals. This work should focus on concrete models and pictorial representations, rather than relying solely on the algorithm. The use of symbolic notations involves having students record the answers to computations (2.25 x 3 = 6.75), but this work should not be done without models or pictures. This standard includes students’ reasoning and explanations of how they use models, pictures, and strategies.

Students should be able to express that when they add decimals they add tenths to tenths and hundredths to hundredths. So, when they are adding in a vertical format (numbers beneath each other), it is important that they write numbers with the same place value beneath each other. This understanding can be reinforced by connecting addition of decimals to their understanding of addition of fractions. Adding fractions with denominators of 10 and 100 is a standard in fourth grade. Examples: a) 4 - 0.3 = _____ 3 tenths subtracted from 4 wholes. The wholes must be divided into tenths. 7 or 3.7. 10 b) An area model can be useful for illustrating products. The answer is 3 c) Find the number in each group or share. MAFS.5.NBT.2.7: Students be encouraged to apply a fair sharing model separating decimal values into equal parts such as Add, subtract, multiply, and divide decimals to hundredths, usingshould concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.

He has to cut pieces of rope that are 0.2 meters long. How many can he cut? To divide to find the number of groups, a student might: draw a segment to represent 1.6 meters. In doing so, he would count in tenths to identify the 6 tenths, and be able to identify the number of 2 tenths within the 6 tenths. The student can then extend the idea of counting by tenths to divide the one meter into tenths and determine that there are 5 more groups of 2 tenths. 10 , a student 10 might think of 1.6 as 16 tenths. Counting 2 tenths, 4 tenths, 6 tenths, . . .16 tenths, a student can count 8 groups of 2 tenths. count groups of 2 tenths without the use of models or diagrams.

Pacing and Sequencing Chart Fifth Grade Mathematics Florida Standards 2015 - 2016 MAFS.5.NF.2.7: Apply and extend previous understandings of division to divide unit fractions by whole numbers and whole numbers by unit fractions. This is the first time students are dividing with fractions. In fifth grade, students experience division problems with whole number divisors and unit fraction dividends or with unit fraction divisors and whole number dividends. Students extend their understanding of the meaning of fractions, how many unit fractions are in a whole, and their understanding of multiplication and division as involving equal groups or shares and the number of objects in each group/share. In sixth grade, they will use this foundational understanding to divide more complex fractions and develop abstract methods of dividing with fractions. a. Interpret division of a unit fraction by a non-zero whole number, and compute such quotients. For Examples: a) Knowing the number of groups/shares and how many/much in each group/share: example, create a story context for 1 1 Four students sitting at a table were given of a pan of brownies to share.

The ordered pair names a point in the plane (x, y). define a coordinate system, with the intersection of the lines (the origin) arranged to coincide with the 0 on each line and a given point in the plane located by using an ordered pair of numbers, called its coordinates. Understand that the first number indicates how far to travel from the origin in the direction of one axis, and the second number indicates how far to travel in the direction of the second axis, with the convention that the names of the two axes and the coordinates correspond (e.g., x-axis and x-coordinate, y-axis and y-coordinate).

Pacing and Sequencing Chart Fifth Grade Mathematics Florida Standards 2015 - 2016 MAFS.5.OA.2.3: This standard extends the work from fourth grade, where students generate numerical patterns when they are given one rule. In fifth grade, students are given two rules and generate two numerical patterns. The graphs that are created should be line graphs to represent the pattern. Generate two numerical patterns using two given rules. Identify apparent relationships between corresponding terms. Form ordered pairs consisting of corresponding terms from the two patterns, and graph Example: the ordered pairs on a coordinate plane. For example, a) Use the rule “add 3” to write a sequence of numbers. Starting with a 0, students write 0, 3, 6, 9, 12, . . . Use the rule “add 6” to write a sequence of numbers. Starting with 0, students write 0, 6, 12, 18, 24, . . given the rule “Add 3” and the starting number 0, and After comparing these two sequences, the students notice that each term in the second sequence is twice the corresponding given the rule “Add 6” and the starting number 0, terms of the first sequence. One way they justify this is by describing the patterns of the terms. Their justification may include generate terms in the resulting sequences, and some mathematical notation (see example below). A student may explain that both sequences start with zero and to generate observe that the terms in one sequence are twice the each term of the second sequence he/she added 6, which is twice as much as was added to produce the terms in the first corresponding terms in the other sequence. Explain sequence. Students may also use the distributive property to describe the relationship between the two numerical patterns by informally why this is so. reasoning that 6 + 6 + 6 = 2 (3 + 3 + 3). 0, +6 +3 6, 3, +6 +3 12, 6, +3 +618, 9, +6 +312, . . . 24,. . . b) Once students can describe that the second sequence of numbers is twice the corresponding terms of the first sequence, the terms can be written in ordered pairs and then graphed on a coordinate grid. They should recognize that each point on the graph represents two quantities in which the second quantity is twice the first quantity. Ordered pairs MAFS.5.MD.3.3: Students’ prior experiences with volume were limited to liquid volume. As students develop their understanding of volume they understand that a 1-unit by 1-unit by 1-unit cube is the standard unit for measuring volume. This cube has a length of 1 unit, a width of 1 Recognize volume as an attribute of solid figures and unit and a height of 1 unit and is called a cubic unit. This cubic unit is written with an exponent of 3 (e.g., in3, m3). Students connect this understand concepts of volume measurement. notation to their understanding of powers of 10 in our place value system. Models of cubic inches, cubic centimeters, cubic feet, etc., are a. A cube with side length 1 unit, called a “unit cube” is helpful in developing an image of a cubic unit. Students estimate how many cubic yards would be needed to fill the classroom or how said to have “one cubic unit” of volume, and can be many cubic centimeters would be needed to fill a pencil box. used to measure volume. b. A solid figure which can be packed without gaps or overlaps using n unit cube is said to have a volume of n cubic units.

Pacing and Sequencing Chart Fifth Grade Mathematics Florida Standards 2015 - 2016 MAFS.5.MD.3.4: Students understand that same sized cubic units are used to measure volume. They select appropriate units to measure volume. For example, they make a distinction between which units are more appropriate for measuring the volume of a gym and the volume of a box Measure volumes by counting unit cubes, using cubic of books. They can also improvise a cubic unit using any unit as a length (e.g., the length of their pencil). Students can apply these ideas cm, cubic in., cubic ft., and improvised units. by filling containers with cubic units (wooden cubes) to find the volume. Students need multiple opportunities to measure volume by filling rectangular prisms with cubes. By looking at the relationship between MAFS.5.MD.3.5: the length, the width, and the height, they develop understanding of both formulas and explore how these ideas would apply to other Relate volume to the operations of multiplication and prisms. Students use the associative property of multiplication and decomposition of numbers using factors to investigate rectangular addition and solve real world and mathematical prisms with a given number of cubic units. problems involving volume. Examples: a) When given 24 cubes, students make as many rectangular prisms as possible with a volume of 24 cubic units. Students build the a.

MAFS.5.MD.1.1: Convert among different-sized standard measurement units (i.e., km, m, cm; kg, g; lb., oz.; l, ml; hr., min., sec.) within a given measurement system (e.g., convert 5 cm to 0.05 m), and use these conversions in solving multistep, real world problems. In fifth grade, students build on their prior knowledge of related measurement units to determine equivalent measurements. Prior to making actual conversions, they examine the units to be converted, determine if the converted amount will be more or less units than the original unit, and explain their reasoning. They use several strategies to convert measurements. When converting metric measurement, students apply their understanding of place value and decimals. (This standard may be carried over into the fourth nine weeks, if FSA testing schedule allows.)

MAFS.5.MD.2.2: Make a line plot to display a data set of measurements in fractions 1 1 1 of a unit ( , , ). Use operations on fractions for this grade to 2 4 8 solve problems involving information presented in line plots. For example, given different measurements of liquid in identical beakers, find the amount of liquid each beaker would contain if the total amount in all the beakers were redistributed equally. This standard provides a context for students to work with fractions by measuring objects to one-eighth of a unit. This includes length, mass, and liquid volume. Students are making a line plot of this data and then adding and subtracting fractions based on data in the line plot. Example: Ten beakers, measured in liters, are filled with a liquid. Liquid in Beakers Amount of Liquid (in Liters) The line plot above shows the amount of liquid in liters in 10 beakers. If the liquid is redistributed equally, how 5 much liquid would each beaker have? 16 Students apply their understanding of operations with fractions. They use either addition and/or multiplication to determine the total number of liters in the beakers. Then the sum of the liters is shared evenly among the ten beakers.

Pacing and Sequencing Chart Fifth Grade Mathematics Florida Standards 2015 - 2016 MAFS.5.G.2.3: Understand that attributes belonging to a category of twodimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles. MAFS.5.G.2.4: Classify and organize two-dimensional figures into Venn diagrams based on the attributes of the figures. This standard calls for students to reason about the attributes (properties) of shapes. Students should have many opportunities to discuss the properties of shapes. Examples: a) Do all quadrilaterals have right angles? No b) A parallelogram has 4 sides with both sets of opposite sides parallel. What types of quadrilaterals are parallelograms? square, rectangle, and rhombus c) Regular polygons have all of their sides and angles congruent. Name or draw some regular polygons. d) All rectangles have 4 right angles. Squares have 4 right angles so they are also rectangles. True or False? e) A trapezoid has 2 sides parallel so it must be a parallelogram. True or False? This standard builds on what was done in fourth grade. Figures from previous grades include polygon, rhombus/rhombi, rectangle, square, triangle, quadrilateral, pentagon, hexagon, cube, trapezoid, half/quarter circle, and circle. Properties of a figure may include: Properties of sides—parallel, perpendicular, congruent, number of sides Properties of angles—types of angles, congruent Lines of symmetry Examples: A right triangle can be both scalene and isosceles, but not equilateral. A scalene triangle can be right, acute or obtuse. Triangles can be classified by angles and sides: Examples: Right: The triangle has one angle that measures 90º. Acute: The triangle has exactly three angles that measure between 0º and 90º. Obtuse: The triangle has exactly one angle that measures greater than 90º and less than 180º. Equilateral: All sides of the triangle are the same length. Isosceles: At least two sides of the triangle are the same length. Scalene: No sides of the triangle are the same length.

Pacing and Sequencing Chart Fifth Grade Mathematics Florida Standards 2015 - 2016 FIFTH GRADE – CRITICAL AREAS OF FOCUS In Grade 5, instructional time should focus on three critical areas: (1) developing fluency with addition and subtraction of fractions, and developing understanding of the multiplication of fractions and of division of fractions in limited cases (unit fractions divided by whole numbers and whole numbers divided by unit fractions); (2) extending division to 2-digit divisors, integrating decimal fractions into the place value system and developing understanding of operations with decimals to hundredths, and developing fluency with whole number and decimal operations; and (3) developing understanding of volume. (1) Students apply their understanding of fractions and fraction models to represent the addition and subtraction of fractions with unlike denominators as equivalent calculations with like denominators. They develop fluency in calculating sums and differences of fractions, and make reasonable estimates of them. Students also use the meaning of fractions, of multiplication and division, and the relationship between multiplication and division to understand and explain why the procedures for multiplying and dividing fractions make sense. (Note: this is limited to the case of dividing unit fractions by whole numbers and whole numbers by unit fractions.) (2) Students develop understanding of why division procedures work based on the meaning of base-ten numerals and properties of operations. They finalize fluency with multi-digit addition, subtraction, multiplication, and division. They apply their understandings of models for decimals, decimal notation, and properties of operations to add and subtract decimals to hundredths. They develop fluency in these computations, and make reasonable estimates of their results. Students use the relationship between decimals and fractions, as well as the relationship between finite decimals and whole numbers (i.e., a finite decimal multiplied by an appropriate power of 10 is a whole number), to understand and explain why the procedures for multiplying and dividing finite decimals make sense. They compute products and quotients of decimals to hundredths efficiently and accurately. (3) Students recognize volume as an attribute of three-dimensional space. They understand that volume can be measured by finding the total number of same-size units of volume required to fill the space without gaps or overlaps. They understand that a 1-unit by 1-unit by 1-unit cube is the standard unit for measuring volume. They select appropriate units, strategies, and tools for solving problems that involve estimating and measuring volume. They decompose three-dimensional shapes and find volumes of right rectangular prisms by viewing them as decomposed into layers of arrays of cubes. They measure necessary attributes of shapes in order to determine volumes to solve real world and mathematical problems.

The associated equations, which have the total on the left of the equal sign, help children understand that the = sign does not always mean makes or results in but always does mean is the same number as. 2Either addend can be unknown, so there are three variations of these problem situations. Both Addends Unknown is a productive extension of this basic situation, especially for small numbers less than or equal to 10. 3For the Bigger Unknown or Smaller Unknown situations, one version directs the correct operation (the version using more for the bigger unknown and using less for the smaller unknown). The other versions are more difficult. 6Adapted from Box 2-4 of Mathematics Learning in Early Childhood, National Research Council (2009, pp. 32, 33).

How much does the red hat cost? 4The language in the array examples shows the easiest form of array problems. A harder form is to use the terms rows and columns: The apples in the grocery window are in 3 rows and 6 columns. How many apples are in there? Both forms are valuable. 5Area involves arrays of squares that have been pushed together so that there are no gaps or overlaps, so array problems include these especially important measurement situations. 7The first examples in each cell are examples of discrete things. These are easier for students and should be given before the measurement examples. Common Operation Situations and Properties, page 2 of 3, Brevard Public Schools, 2015 – 2016 TABLE 3.

Make conjectures and prove or disprove them Look for and create efficient strategies Be precise with words, numbers, and symbols Use tools and technology strategically What Constitutes a Cognitively Demanding Task? Lower-level demands (memorization) • Involve either reproducing previously learned facts, rules, formulas, or definitions or committing facts, rules, formulas or definitions to memory. • Cannot be solved using procedures because a procedure does not exist or because the time frame in which the task is being completed is too short to use a procedure • Are not ambiguous. Such tasks involve the exact reproduction of previously seen material, and what is to be reproduced is clearly and directly stated. • Have no connection to the concepts or meaning that underlie the facts, rules, formulas, or definitions being learned or reproduced. Lower-level demands (procedures without connections to meaning) • Are algorithmic. Use of the procedure either is specifically called for or is evident from prior instruction, experience, or placement of the task. • Require limited cognitive demand for successful completion. Little ambiguity exists about what needs to be done and how to do it. • Have no connection to concepts or meaning that underlie the procedure being used. • Are focused on producing correct answers instead of on developing mathematical understanding. • Require no explanation or explanations that focus solely on describing the procedure that was used. Higher-level demands (procedures with connections to meaning) • Focus students’ attention on the use of procedures for the purpose of developing deeper levels of understanding of mathematical concepts and ideas. • Suggest explicitly or implicitly pathways to follow that are broad general procedures that have close connections to underlying conceptual ideas as opposed to narrow algorithms that are opaque with respect to underlying concepts. • Usually are represented in multiple ways, such as visual diagrams, manipulatives, symbols, and problem situations. Making connections among multiple representations helps develop meaning. • Require some degree of cognitive effort. Although general procedures may be followed, they cannot be followed mindlessly. Students need to engage with conceptual ideas that underlie the procedures to complete the task successfully and that develop understanding. Higher-level demands (doing mathematics) • Require complex and non-algorithmic thinking - a predictable, well-rehearsed approach or pathway is not explicitly suggested by the task, task instructions, or a worked-out example. • Require students to explore and understand the nature of mathematical concepts, processes, or relationships. • Demand self-monitoring or self-regulation of one’s own cognitive processes. • Require students to access relevant knowledge and experiences and make appropriate use of them in working through the task. • Require considerable cognitive effort and may involve some level of anxiety for the student because of the unpredictable nature of the solution process required.

Key Ideas in the Mathematics Florida Standards (MAFS) Focus: Greater focus on fewer topics Focus deeply on the standards for mastery and the ability to transfer skills. Focus deeply on the major work of each grade as follows: In grades K-2: Concepts, skills, problem solving related to addition and subtraction. In grades 3-5: Concepts, skills, and problem solving related to multiplication and division of whole numbers and fractions. In grade 6: Ratios and proportional relationships, and early algebraic expressions and equations. This focus will enable students to gain strong foundations, including a solid understanding of concepts, and the ability to apply the math they know to solve problems inside and outside the classroom. Coherence: Linking topics and thinking across grades Coherence is about making math make sense. Mathematics is a coherent body of knowledge made up of interconnected concepts. The standards are designed around coherent progressions from grade to grade. Learning is carefully connected across grades so that students can build new understanding onto foundations built in previous years. Each standard is not a new event, but an extension of previous learning. It is critical to think across grade levels and examine the progressions to see how major content is developed across grades. Rigor: Calls for a balance of tasks that require conceptual understanding, procedural skills and fluency, and application of mathematics to solve problems Rigor refers to deep, authentic command of mathematical concepts. The following three aspects of rigor must be pursued with equal intensity to help students meet the standards: Conceptual understanding: The standards call for conceptual understanding of key concepts. Students must be able to access concepts from a number of perspectives. This will allow them to see math as more than a set of mnemonics or discrete procedures. Procedural skills and fluency: The standards call for speed and accuracy in calculation with a balance of practice and understanding. Students must practice simple calculations such as single-digit multiplication with meaning, in order to have access to more complex concepts and procedures. Application: The standards call for students to have solid conceptual understanding and procedural fluency. They are expected to apply their understanding and procedural skills in mathematics to problem solving situations. -Adapted from www.corestandards.org Standards for Mathematical Practice The Standards for Mathematical Practice describe behaviors that all students will develop in the Common Core Standards. These practices rest on important “processes and proficiencies” including problem solving, reasoning and proof, communication, representation, and making connections. These practices will allow students to understand and apply mathematics with confidence. When given a problem, I can make a plan to solve it and check my answer. 1.

Below are a few examples of how these Practices may be integrated into tasks that students complete. Practice Explanation and Example 1. Make sense of problems and persevere in solving them. Mathematically proficient students in fifth grade solve problems by applying their understanding of operations with whole numbers, decimals, and fractions including mixed numbers. They solve problems related to volume and measurement conversions. Students seek the meaning of a problem and look for efficient ways to represent and solve it. They may check their thinking by asking themselves, “What is the most efficient way to solve the problem?”, “Does this make sense?”, and “Can I solve the problem in a different way?”. 2. Reason abstractly and quantitatively. Mathematically proficient students in fifth grade should recognize that a number represents a specific quantity. They connect quantities to written symbols and create a logical representation of the problem at hand, considering both the appropriate units involved and the meaning of quantities. They extend this understanding from whole numbers to their work with fractions and decimals. Students write simple expressions that record calculations with numbers and represent or round numbers using place value concepts. 3. Construct viable arguments and critique the reasoning of others. Mathematically proficient students in fifth grade may construct arguments using concrete referents, such as objects, pictures, and drawings. They explain calculations based upon models and properties of operations and rules that generate patterns. They demonstrate and explain the relationship between volume and multiplication. They refine their mathematical communication skills as they participate in mathematical discussions involving questions like “How did you get that?” and “Why is that true?”. They explain their thinking to others and respond to others’ thinking. 4. Model with mathematics. Mathematically proficient students in fifth grade experiment with representing problem situations in multiple ways including numbers, words (mathematical language), drawing pictures, using objects, making a chart, list, or graph, creating equations, etc. Students need opportunities to connect these different representations and explain the connections. They should be able to use all of these representations as needed. Fifth graders should evaluate their results in the context of the situation and whether the results make sense. They also evaluate the utility of models to determine which models are most useful and efficient to solve problems. Standards for Mathematical Practice, (from North Carolina Department of Education, http://www.ncpublicschools.org/), Fifth Grade, page 1 of 2, 2013 - 2014 Practice Explanation and Example 5. Use appropriate tools strategically. Mathematically proficient students in fifth grade consider the available tools (including estimation) when solving a mathematical problem and decide when certain tools might be helpful. For instance, they may use unit cubes to fill a rectangular prism and then use a ruler to measure the dimensions. They use graph paper to accurately create graphs and solve problems or make predictions from real- world data. 6. Attend to precision. Mathematically proficient students in fifth grade continue to refine their mathematical communication skills by using clear and precise language in their discussions with others and in their own reasoning. Students use appropriate terminology when referring to expressions, fractions, geometric figures, and coordinate grids. They are careful about specifying units of measure and state the meaning of the symbols they choose. For instance, when figuring out the volume of a rectangular prism, they record their answers in cubic units. 7. Look for and make use of structure. Mathematically proficient students in fifth grade look closely to discover a pattern or structure. For instance, students use properties of operations as strategies to add, subtract, multiply, and divide with whole numbers, fractions, and decimals. They examine numerical patterns and relate them to a rule or a graphical representation. 8. Look for and express regularity in repeated reasoning. Mathematically proficient students in fifth grade use repeated reasoning to understand algorithms and make generalizations about patterns. Students connect place value and their prior work with operations to understand algorithms to fluently multiply multi-digit numbers and perform all operations with decimals to hundredths. Students explore operations with fractions with visual models and begin to formulate generalizations.

Understand the absolute value of a rational number as its distance from 0 on the number line; interpret absolute value as magnitude for a positive or negative quantity in real-world situation. For example, for an account balance of -30 dollars, write |-30| = 30 to describe the size of debt in dollars. d. Distinguish comparisons of absolute value from statements about order. For example, recognize that an account balance less than -30 dollars represents a debt greater than 30 dollars. 6.NS.3.8: Solve real-world and mathematical problems by graphing points in all four quadrants of the coordinate plane. Include use of coordinates and absolute value to find distances between points with the same first coordinate or the same second coordinate. Domain Progression, Brevard Public Schools, 2013-2014 Page 18 of 22 EXPRESSIONS AND EQUATIONS Sixth Grade Apply and extend previous understandings of arithmetic to algebraic expressions. 6.EE.1.1: Write and evaluate numerical expressions involving whole number exponents. 6.EE.1.2: Write, read, and evaluate expressions in which letters stand for numbers. a. Write expressions that record operations with numbers and with letters standing for numbers. For example, express the calculation “Subtract y from 5” as 5 – y. b. Identify parts of an expression using mathematical terms (sum, term, product, factor, quotient, coefficient); view one or more parts of an expression as a single entity. For example, describe the expression 2(8 + 7) as a product of two factors; view (8 + 7) as both a single entity and a sum of two terms. c. Evaluate expressions at specific values of their variables. Include expressions that arise from formulas used in real-world problems. Perform arithmetic operations, including those involving whole number exponents, in the conventional order when there are no parentheses to specify a particular order (Order of Operations). For example, use the formulas V = s3 and A = 6s2 to find the volume and surface area of a cube with sides of length s = 1 . 2 6.EE.1.3: Apply the properties of operations to generate equivalent expressions. For example, apply the distributive property to the expression 3(2 + x) to produce the equivalent expression 6 + 3x; apply the distributive property to the expression 24x + 18y to produce the equivalent expression 6(4x + 3y); apply properties of operations to y + y + y to produce the equivalent expression 3y. Domain Progression, Brevard Public Schools, 2013-2014 Seventh Grade Use properties of operations to generate equivalent expressions. 7.EE.1.1: Apply properties of operations as strategies to add, subtract, factor, and expand linear expressions with rational coefficients. 7.EE.1.2: Understand that rewriting an expression in different forms in a problem context can shed light on the problem and how the quantities in it are related. For example, a + 0.05a = 1.05a means that “increase by 5%” is the same as “multiply by 1.05”. Solve real-life and mathematical problems using numerical and algebraic expressions and equations. 7.EE.2.3: Solve multi-step real-life and mathematical problems posed with positive and negative rational numbers in any form (whole numbers, fractions, and decimals) using tools strategically. Apply properties of operations to calculate with numbers in any form; convert between forms as appropriate; and assess the reasonableness of answers using mental computation and estimation strategies. For example: If a woman making $25 an hour gets a 10% raise, she will make an 1 of her salary an hour, or $2.50, for a new salary of $27.50. If you want 10 3 1 to place a towel bar 9 inches long in the center of a door that is 27 inches 2 4 additional wide, you will need to place the bar about 9 inches from each edge; this estimate can be used as a check on the exact computation. 7.EE.2.4: Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities. Page 19 of 22 Sixth Grade Seventh Grade 6.EE.1.4: Identify when two expressions are equivalent (e.g., when the two expressions name the same number regardless of which value is substituted into them). For example, the expressions y + y + y and 3y are equivalent because they name the same number regardless of which number y stands for. Reason about and solve one-variable equations and inequalities. 6.EE.2.5: Understand solving an equation or inequality as a process of answering a question: which values from a specified set, if any, make the equation or inequality true? Use substitution to determine whether a given number in a specified set makes an equation or inequality true. a. Solve word problems leading to equations of the form px + q = r and p(x + q) = r, where p, q, and r are specific rational 6.EE.2.6: Use variables to represent numbers and write expressions when solving a numbers. Solve equations of these forms fluently. Compare an real-world or mathematical problem; understand that a variable can algebraic solution to an arithmetic solution, identifying the sequence represent an unknown number, or, depending on the purpose at hand, any of the operations used in each approach. number in a specified set. For example, the perimeter of a rectangle is 54 cm. Its length is 6 cm. What is its 6.EE.2.7: Solve real-world and mathematical problems by writing and solving width? equations of the form x + p = q and px = q for cases in which p, q and x are b. Solve word problems leading to inequalities of the form all non-negative rational numbers. px + x > r or px + q < r, where p, q, and r are specific rational 6.EE.2.8: Write an inequality of the form x > c or x < c to represent a constraint or numbers. Graph the solution set of the inequality and interpret it in the condition in a real-world or mathematical problem. Recognize that context of the problem. inequalities of the form x > c or x < c have infinitely many solutions; For example, as a salesperson, you are paid $50 per week plus $3 per sale. This represent solutions of such inequalities on number line diagrams. week you want your pay to be a least $100. Write an inequality for the number of sales you need to make and describe the solutions. Represent and analyze quantitative relationships between dependent and independent variables. 6.EE.3.9: Use variables to represent two quantities in a real-world problem that change in relationship to one another; write an equation to express one quantity, thought of as the dependent variable, in terms of the other quantity, thought of as the independent variable. Analyze the relationship between the dependent and the independent variables using graphs and tables, and relate these to the equation. For example, in a problem involving motion at constant speed, list and graph ordered pairs of distances and times, and write the equation d = 65t to represent the relationship between distance and time. Domain Progression, Brevard Public Schools, 2013-2014 Page 20 of 22 STATISTICS AND PROBABILITY Sixth Grade Seventh Grade Develop understanding of statistical variability. Use random sampling to draw inferences about a population. 6.SP.1.1: Recognize a statistical question as one that anticipates variability in the data related to the question and accounts for it in the answers. For example, “How old am I?” is not a statistical question, but “How old are the students in my school?” is a statistical question because one anticipates variability in students’ ages. 7.SP.1.1: Understand that statistics can be used to gain information about a population by examining a sample of the population; generalizations about a population from a sample are valid only if the sample is representative of that population. Understand that random sampling tends to produce representative samples and support valid inferences. 6.SP.1.2: Understand that a set of data collected to answer a statistical question has a distribution which can be described by its center, spread, and overall shape. 7.SP.1.2: Use data from a random sample to draw inferences about a population with an unknown characteristic of interest. Generate multiple samples (or simulated samples) of the same size to gauge the variation in estimates or predictions. 6.SP.1.3: Recognize that a measure of center for a numerical data set summarizes For example, estimate the mean word length in a book by randomly sampling all of its values with a single number, while a measure of variation words from the book; predict the winner of a school election based on randomly describes how its values vary with a single number. sampled survey data. Gauge how far off the estimate or prediction might be. Summarize and describe distributions. 6.SP.2.4: Display numerical data in plots on a number line, including dot plots, histograms, and box plots. 6.SP.2.5: Summarize numerical data sets in relation to their context, such as by: a. Reporting the number of observations. b. Describing the nature of the attribute under investigation, including how it was measured and its units of measurement. c. Giving quantitative measures of center (median and/or mean) and variability (interquartile range and/or mean absolute deviation), as well as describing any overall pattern and any striking deviations from the overall pattern with reference to the context in which the data were gathered. d. Relating the choice of measures of center and variability to the shape of the data distribution and the context in which the data were gathered. Domain Progression, Brevard Public Schools, 2013-2014 Draw informal comparative inferences about two populations. 7.SP.2.3: Informally assess the degree of visual overlap of two numerical data distributions with similar variabilities, measuring the difference between the centers by expressing it as a multiple of a measure of variability. For example, the mean height of players on the basketball team is 10 cm greater than the mean height of players on the soccer team, about twice the variability (mean absolute deviation) on either team; on a dot plot, the separation between the two distributions of heights is noticeable. 7.SP.2.4: Use measures of center and measures of variability for numerical data from random samples to draw informal comparative inferences about two populations. For example, decide whether the words in a chapter of a seventh grade science book are generally longer than the words in a chapter of a fourth grade science book. Page 21 of 22 Sixth Grade Seventh Grade Investigate chance processes and develop, use, and evaluate probability models. 7.SP.3.5: Understand that the probability of a chance event is a number between 0 and 1 that expresses the likelihood of the event occurring. Larger numbers indicate greater likelihood. A probability near 0 indicates an unlikely event, a probability 1 around indicates an event that is neither unlikely nor likely, and a probability 2 near 1 indicates a likely event. 7.SP.3.6: Approximate the probability of a chance event a probability around by collecting data on the chance process that produces it and observing its long-run relative frequency, and predict the approximate relative frequency given the probability. For example, when rolling a number cube 600 times, predict that a 3 or 6 would be rolled roughly 200 times, but probably not exactly 200 times. 7.SP.3.7: Develop a probability model and use it to find probabilities of events. Compare probabilities from a model to observed frequencies; if the agreement is not good, explain possible sources of the discrepancy. a. Develop a uniform probability model by assigning equal probability to all outcomes, and use the model to determine probabilities of events. For example, if a student is selected at random from a class, find the probability that Jane will be selected and the probability that a girl will be selected. b. Develop a probability model (which may not be uniform) by observing frequencies in data generated from a chance process. For example, find the approximate probability that a spinning penny will land heads up or that a tossed paper cup will land open-end down. Do the outcomes for the spinning penny appear to be equally likely passed on the observed frequencies? 7.SP.3.8: Find probabilities of compound events using organized lists, tables, tree diagrams, and simulation. a. Understand that, just as with simple events, the probability of a compound event is the fraction of outcomes in the sample space for which the compound event occurs. b. Represent sample spaces for compound events using methods such as organized lists, tables, and tree diagrams. For an event described in everyday language (e.g., “rolling double sixes”) identify the outcomes in the sample space which compose the event. c. Design and use a simulation to generate frequencies for compound events. For example, use random digits as a simulation tool to approximate the answer to the question: If 40% of donors have type A blood, what is the probability that it will take at least 4 donors to find one with type A blood? Domain Progression, Brevard Public Schools, 2013-2014 Page 22 of 22 FIFTH GRADE DOMAIN/CLUSTER DESCRIPTORS AND CLARIFICATION Domain: Operations and Algebraic Thinking Cluster: Write and interpret numerical expressions. Students should be given ample opportunities to explore numerical expressions with mixed operations. This is the foundation for evaluating numerical and algebraic expressions that will include whole number exponents in Grade 6. There are conventions (rules) determined by mathematicians that must be learned with no conceptual basis. For example, multiplication and division are always done before addition and subtraction. Begin with expressions that have two operations without any grouping symbols (multiplication or division combined with addition or subtraction) before introducing expressions with multiple operations. Using the same digits, with the operations in a different order, have students evaluate the expressions and discuss why the value of the expression is different. For example, have students evaluate 5 × 3 + 6 and 5 + 3 × 6. Discuss the rules that must be followed. Have students insert parentheses around the multiplication or division part in an expression. A discussion should focus on the similarities and differences in the problems and the results. This leads to students being able to solve problem situations which require that they know the order in which operations should take place. After students have evaluated expressions without grouping symbols, present problems with one grouping symbol, beginning with parentheses, then in combination with brackets and/or braces. Have students write numerical expressions in words without calculating the value. This is the foundation for writing algebraic expressions. Then, have students write numerical expressions from phrases without calculating them. Common Misconceptions Students may believe the order in which a problem with mixed operations is written is the order to solve the problem. Allow students to use calculators to determine the value of the expression, and then discuss the order the calculator used to evaluate the expression. Fifth Grade Domain and Cluster Descriptors and Clarifications (from Ohio Department of Education, www.ode.state.oh.us/), page 1 of 11, 2013-2014 FIFTH GRADE DOMAIN/CLUSTER DESCRIPTORS AND CLARIFICATION Domain: Operations and Algebraic Thinking Cluster: Analyze patterns and relationships. The graph of both sequences of numbers is a visual representation that will show the relationship between the two sequences of numbers. Encourage students to represent the sequences in T-charts so that they can see a connection between the graph and the sequences. Common Misconceptions Students reverse the points when plotting them on a coordinate plane. They count up first on the y-axis and then count over on the x-axis. The location of every point in the plane has a specific place. Have students plot points where the numbers are reversed such as (4, 5) and (5, 4). Begin with students providing a verbal description of how to plot each point. Then, have them follow the verbal description and plot each point. Fifth Grade Domain and Cluster Descriptors and Clarifications (from Ohio Department of Education, www.ode.state.oh.us/), page 2 of 11, 2013-2014 FIFTH GRADE DOMAIN/CLUSTER DESCRIPTORS AND CLARIFICATION Domain: Number and Operations in Base Ten Cluster: Understand the place value system. In Grade 5, the concept of place value is extended to include decimal values to thousandths. The strategies for Grades 3 and 4 should be drawn upon and extended for whole numbers and decimal numbers. For example, students need to continue to represent, write and state the value of numbers including decimal numbers. For students who are not able to read, write, and represent multi-digit numbers, working with decimals will be challenging. Money is a good medium to compare decimals. Present contextual situations that require the comparison of the cost of two items to determine the lower or higher priced item. Students should also be able to identify how many pennies, dimes, dollars, and ten dollars, etc., are in a given value. Help students make connections between the number of each type of coin and the value of each coin, and the expanded form of the number. Build on the understanding that it always takes ten of the number to the right to make the number to the left. Number cards, number cubes, spinners, and other manipulatives can be used to generate decimal numbers. For example, have students roll three number cubes, then create the largest and smallest number to the thousandths place. Ask students to represent the number with numerals and words. Common Misconceptions A misconception that is directly related to comparing whole numbers is the idea that the more digits the number has the greater the number. With whole numbers, a 5-digit number is always greater than a 1-, 2-, 3-, or 4-digit number. However, with decimals, a number with one decimal place may be greater than a number with two or three decimal places. For example, 0.5 is greater than 0.12, 0.009 or 0.499. One method for comparing decimals it to make all numbers have the same number of digits to the right of the decimal point by adding zeros to the number, such as 0.500, 0.120, 0.009 and 0.499. A second method is to use a place-value chart to place the numerals for comparison. Fifth Grade Domain and Cluster Descriptors and Clarifications (from Ohio Department of Education, www.ode.state.oh.us/), page 3 of 11, 2013-2014 FIFTH GRADE DOMAIN/CLUSTER DESCRIPTORS AND CLARIFICATION Domain: Number and Operations in Base Ten Cluster: Perform operations with multi-digit whole numbers and with decimals to hundredths. Because students have used various models and strategies to solve problems involving multiplication with whole numbers, they should be able to transition to using standard algorithms effectively. With guidance from the teacher, they should understand the connection between the standard algorithm and their strategies. Connections between the algorithm for multiplying multi-digit whole numbers and strategies such as partial products or lattice multiplication are necessary for students’ understanding. The multiplication can also be done without listing the partial products by multiplying the value of each digit from one factor by the value of each digit from the other factor. Understanding of place value is vital in using the standard algorithm. As students develop efficient strategies to do whole number operations, they should also develop efficient strategies with decimal operations. Students should learn to estimate decimal computations before they compute with pencil and paper. The focus on estimation should be on the meaning of the numbers and the operations, not on how many decimal places are involved. Have students use estimation to find the product by using exactly the same digits in one of the factors with the decimal point in a different position each time. For example, have students estimate the product of 275 × 3.8, 27.5 × 3.8, and 2.75 × 3.8, and discuss why the estimates should or should not be the same. Common Misconceptions Students might compute the sum or difference of decimals by lining up the right-hand digits as they would whole number. For example, in computing the sum of 15.34 + 12.9, students will write the problem in this manner: 15.34 + 12.9 16.63 To help students add and subtract decimals correctly, have them first estimate the sum or difference. Providing students with a decimal-place value chart will enable them to place the digits in the proper place. Students should understand that the decimal points should be lined up when writing an addition or subtraction problem vertically. Fifth Grade Domain and Cluster Descriptors and Clarifications (from Ohio Department of Education, www.ode.state.oh.us/), page 4 of 11, 2013-2014 FIFTH GRADE DOMAIN/CLUSTER DESCRIPTORS AND CLARIFICATION Domain: Number and Operations – Fractions Cluster: Use equivalent fractions as a strategy to add and subtract fractions. To add or subtract fractions with unlike denominators, students use their understanding of equivalent fractions to create fractions with the same denominators. Start with problems that require the changing of one of the fractions and progress to changing both fractions. Allow students to add and subtract fractions using different strategies such as number lines, area models, and fraction bars or strips. Have students share their strategies and discuss commonalities in them. Students need to develop the understanding that when adding or subtracting fractions, the fractions must refer to the same whole. Any models used must refer to the same whole. Students may find that a circular model might not be the best model when adding or subtracting fractions. The concept of adding or subtracting fractions with unlike denominators will develop through solving problems. Mental computations and estimation strategies should be used to determine the reasonableness of answers. Students need to prove or disprove whether an answer provided for a problem is reasonable. Estimation is about getting useful answers, it is not about getting the right answer. It is important for students to learn which strategy to use for estimation. Students need to think about what might be a close answer. Common Misconceptions Students often mix models when adding, subtracting, or comparing fractions. Students will use a circle for thirds and a rectangle for fourths when comparing fractions with thirds and fourths. Remind students that the representations need to be from the same whole models with the same shape and size. Fifth Grade Domain and Cluster Descriptors and Clarifications (from Ohio Department of Education, www.ode.state.oh.us/), page 5 of 11, 2013-2014 FIFTH GRADE DOMAIN/CLUSTER DESCRIPTORS AND CLARIFICATION Domain: Number and Operations – Fractions Cluster: Apply and extend previous understandings of multiplication and division to multiply and divide fractions. Connect the meaning of multiplication and division of fractions with whole number multiplication and division. Consider area models of multiplication and both sharing and measuring models for division. Ask questions such as, “What does 2 × 3 mean?” and “What does 12 ÷ 3 mean?”. Then, follow with questions for multiplication with fractions, such as, “What does 3 3 3 3 4 × 3 1 3 “What does 4 × 7 mean?” (4 of a set of 7), and “What does 7 × 4 mean?” (7 sets of 4). The meaning of 4 ÷ 1 2 1 (How many 2’s are in 4?) and 1 2 should also be illustrated with models or drawings like: mean?”, 1 ÷ 4 (How many groups of 4 are in 2) Encourage students to use models or drawings to multiply or divide with fractions. Begin with students modeling multiplication and division with whole numbers. Have them explain how they used the model or drawing to arrive at the solution. Models to consider when multiplying or dividing fractions include, but are not limited to: area models using rectangles or squares, fraction strips/bars and sets of counters. Present problem situations and have students use models and equations to solve the problem. It is important for students to develop understanding of multiplication and division of fractions through contextual situations. Common Misconceptions Students may believe that multiplication always results in a larger number. Additionally, students may believe that division always results in a smaller number. Using models when multiplying and dividing with fractions will enable students to see that the results are not always so. Fifth Grade Domain and Cluster Descriptors and Clarifications (from Ohio Department of Education, www.ode.state.oh.us/), page 6 of 11, 2013-2014 FIFTH GRADE DOMAIN/CLUSTER DESCRIPTORS AND CLARIFICATION Domain: Measurement and Data Cluster: Convert like measurement units. Students should gain ease in converting units of measures in equivalent forms within the same system. To convert from one unit to another unit, the relationship between the units must be known. In order for students to have a better understanding of the relationships between units, they need to use measuring tools in class. The number of units must relate to the size of the unit. For example, students have discovered that there are 12 inches in 1 foot and 3 feet in 1 yard. This understanding is needed to convert inches to yards. Using 12-inch rulers and yardsticks, students can see that three of the 12-inch rulers are equivalent to one yardstick (3 × 12 inches = 36 inches; 36 inches = 1 yard). Using this knowledge, students can decide whether to multiply or divide when making conversions. Once students have an understanding of the relationships between units and how to do conversions, they are ready to solve multi-step problems that require conversions within the same system. Allow students to discuss methods used in solving the problems. Begin with problems that allow for renaming the units to represent the solution before using problems that require renaming to find the solution. Common Misconceptions When solving problems that require renaming units, students use their knowledge of renaming the numbers as with whole numbers. Students need to pay attention to the unit of measurement which dictates the renaming and the number to use. The same procedures used in renaming whole numbers should not be taught when solving problems involving measurement conversions. For example, when subtracting 5 inches from 2 feet, students may take 1 foot from the 2 feet and use it as 10 inches. Since there were no inches with the 2 feet, they put 1 with 0 inches and make it 10 inches, when it should be 1 foot 12 inches.

Using a line plot to solve problems involving operations with unit fractions now includes multiplication and division. Revisit using a number line to solve multiplication and division problems with whole numbers. In addition to knowing how to use a number line to solve problems, students also need to know which operation to use to solve problems. Use the tables for common addition, subtraction, multiplication, and division situations (Table 1 and Table 2 in the Common Core State Standards for Mathematics) as a guide to the types of problems students need to solve without specifying the type of problem. Allow students to share methods used to solve the problems. Also have students create problems to show their understanding of the meaning of each operation.

Volume refers to the amount of space that an object takes up and is measured in cubic units, such as cubic inches or cubic centimeters. Students need to experience finding the volume of rectangular prisms by counting unit cubes, in metric and standard units of measure, before the formula is presented. Provide multiple opportunities for students to develop the formula for the volume of a rectangular prism with activities similar to the one described below. Give students one block (a cubic-centimeter or cubic-inch cube), a ruler with the appropriate measure based on the type of cube, and a small rectangular box. Ask students to determine the number of cubes needed to fill the box. Have students share their strategies with the class using words, drawings or numbers. Allow them to confirm the volume of the box by filling the box with cubes of the same size. A right-rectangular prism has three pairs of parallel faces that are all rectangles. Have students build a prism in layers. Then, have students determine the number of cubes in the bottom layer and share their strategies. By stacking geometric solids with cubic units in layers, students can begin understanding the concept of how addition plays a part in finding volume. Students should use multiplication based on their knowledge of arrays and its use in multiplying two whole numbers. This will lead to an understanding of the formula for the volume of a right-rectangular prism, 𝐵 × ℎ, where 𝐵 is the area of the base. Ask what strategies can be used to determine the volume of the prism based on the number of cubes in the bottom layer. Expect responses such as “adding the same number of cubes in each layer as were on the bottom layer” or multiply the number of cubes in one layer times the number of layers.

Students need to understand the underlying structure of the coordinate system and see how axes make it possible to locate points anywhere on a coordinate plane. This is the first time students are working with coordinate planes, and only in the first quadrant. It is important that students create the coordinate grid themselves. This can be related to two number lines and reliance on previous experiences with moving along a number line. Multiple experiences with plotting points are needed. Provide points plotted on a grid and have students name and write the ordered pair. Have students describe how to get to the location. Encourage students to articulate directions as they plot points. Present real-world and mathematical problems and have students graph points in the first quadrant of the coordinate plane. Gathering and graphing data is a valuable experience for students. It helps them to develop an understanding of coordinates and what the overall graph represents. Students also need to analyze the graph by interpreting the coordinate values in the context of the situation. Common Misconceptions When playing games with coordinates or looking at maps, students may think the order in plotting a coordinate point is not important. Have students plot points so that the position of the coordinates is switched. For example, have students plot (3, 4) and (4, 3) and discuss the order used to plot the points. Have students create directions for others to follow so that they become aware of the importance of direction and distance.

This cluster builds from Grade 3 when students described, analyzed, and compared properties of twodimensional shapes. They compared and classified shapes by their sides and angles, and connected these with definitions of shapes. In Grade 4, students built, drew, and analyzed two-dimensional shapes to deepen their understanding of the properties of two-dimensional shapes. They looked at the presence or absence of parallel and perpendicular lines or the presence or absence of angles of a specified size to classify two-dimensional shapes. Now, students classify two-dimensional shapes in a hierarchy based on properties. Details learned in earlier grades need to be used in the descriptions of the attributes of shapes. The more ways that students can classify and discriminate shapes, the better they can understand them. The shapes are not limited to quadrilaterals. Students can use graphic organizers such as flow charts or t-charts to compare and contrast the attributes of geometric figures. Have students create a t-chart with a shape on each side. Have them list attributes of the shapes, such as number of sides, number of angles, types of lines, etc. They need to determine what is alike or different about the two shapes to get a larger classification for the shapes. Pose questions such as, “Why is a square always a rectangle?” and “Why is a rectangle not always a square?”.

By using and comparing a variety of solution strategies students build their understanding of the relationship between addition and subtraction. *The following information regarding addition and subtraction strategies has been adapted from: Van de Walle, J.A., & Lovin, L.H. (2006). Teaching Student-Centered Mathematics, Volume I. Boston: Pearson. See chapters three and four of this book for further clarification of addition and subtraction strategies. Addition Strategies Subtraction Strategies Zero One More/Two More Doubles Near Doubles Sums of Ten Make Ten Ten Plus Invented Commutative Property Associative Property Think-Addition Build Up Through Ten Back Down Through Ten Invented SPECIAL NOTES: Basic facts for addition are combinations of numbers where both addends are less than 10. Subtraction facts correspond to the addition facts. Fluency involves accuracy (correct answer), efficiency (a reasonable amount of steps that does not include counting), and flexibility (using strategies that demonstrate number sense). Every child, including ESE children, can master the basic facts with efficient mental tools. Steps to Mastery: 1) Children must develop an understanding of number relationships and the operations. 2) Children need to develop efficient strategies for fact retrieval. 3) Teachers need to provide practice of selection of strategies once they have been developed. Children who do not learn mental strategies will continue to count on their fingers since they have no other strategies to solve basic addition and subtraction problems. AVOID PREMATURE DRILL: if a child does not know a fact and is given a timed test; the child will revert to counting. Downplay counting on as a strategy because children often get confused as to why they can count for some problems but not others. It is used as a crutch where other strategies would be more efficient. Many of the strategies apply to more than one fact. Therefore, students need to choose the one that works best for them through discussion and justification. Encourage discussion so students can justify and defend their method. This allows the students to hear other methods that might lead to the development of a more effective strategy. Addition and Subtraction Strategies, page 1, 2015 - 2016 NOTE: Counting on is not a sophisticated strategy. Children coming from Kindergarten are expected to recognize small sets of numbers but may count. Children in first and second grade are expected to take the next step by creating and using more sophisticated strategies such as the ones listed below. Addition Strategies (Continued) Note: Zero One addend is always zero The sum of any addend and zero is the original addend. There are 19 facts where zero is one of the addends Be sure to show 0 + 6 and 6 + 0 Children assume that addition sentences result in a larger number This may seem easy; however, students over generalize that an addition sentence always equals a larger sum. One/Two More One addend is 1 or 2 36 facts Students are ready for these activities when they can identify 1 or 2 more without counting Doubles The two addends are the same 0 + 0, 1 + 1, 2 + 2, etc. There are 10 doubles facts These facts will be anchors for other facts (such as 4 + 4 = 8 so 4 + 5 = 9 , see Near-Doubles) Near-Doubles All combinations where one addend is more than the other Note: Some children will double the smaller fact and add up 6 + 6 = 12 so 6 + 7 = 13. Others will double the greater fact and subtract one 7 + 7 = 14 so 7 + 6 = 13 *Be sure students are exposed to both so they can decide which is better for them. Sums of Ten The two addends equal the sum of ten These facts will be anchors for other facts (such as 9 + 1=10, so 9 + 4 becomes 10 + 3) Ten Plus One addend is 10, 10 + 4, 4 + 10 Children need to recognize that a set of ten and a set of 4 total 14 without counting. * This is not an appropriate place for the term 1 ten as regrouping for first graders. The term 1 set of ten not a 1 in the tens place should be used to meet the needs of the early first grade student. Make-Ten These facts all have 8 or 9 as one of the addends Children use 10 as a way to “bridge” to get the sum 6 + 8. Start with 8; decompose the 6 into 4 + 2 add the 2 to 8 and get a sum of 10. 10 and the remaining 4 equals 14 so 6 + 8 = 14. Commutative Property The order of the addends does not change the sum 2+5=5+2 Associative Property The sum is the same regardless of the grouping of the addends. 2 + (6 + 4) = 2 + 10 = 12 Addition and Subtraction Strategies, page 2, 2015 - 2016 Remaining 4 Facts 3+5 3+6 4+7 5+7 The children have learned or discovered strategies to solve the 4 strategies above. Now encourage the students to apply and choose a strategy that will work for them. 7+4 7+5 decompose the 4 into 3 + 1 to make ten, add 1 more decompose the 5 to make 3 + 2, therefore making a ten creating a fact they know (7 + 3 = 10), then add 2 more Invented Students create and/or apply any of the above strategies to other equations. Students will create ways to solve problems that are not noted above. Encourage students to create other ways to solve problems other than counting. Invented strategies are number-oriented, flexible, and constructed by students. Addition Strategies Circle Map Make Ten 7 + 3 = 10 +2 12 Invented (using what I know) 7+5 7 + 7 = 14 7 + 5 = 12 Invented (applying a near double) 7 + 6 = 13 7 + 5 = 12 Addition and Subtraction Strategies, page 3, 2015 - 2016 Subtraction Strategies Think-Addition The student understands subtraction as an unknown addend problem. This strategy works best for sums less than 10 because 64 % of the 100 subtraction facts fall into this category, for example: 9 – 4 (think 4 + 5 = 9) Such facts as 7 – 2 would go along well with 2 more, now think 2 less along with 2 + 5 = 7, so 7 – 2 = 5 Build Up Through Ten This group includes all the facts where the part is either 8 or 9 Start with the 8 or 9 and ask how much to ten and then build up Back Down Through 10 It is most useful for facts where one digit is close to the number it is being subtracted from 14 - 6, remove six from a ten frame and then two more to get the eight Known as decomposing a number leading to a ten in Common Core Invented Students will create ways to solve problems that are not noted above Encourage students to create other ways to solve problems other than counting Circle Map Think addition Build Up Through 10 8+2=10 +4 14 8+6 Back Down Through 10 14 - 8 (4+4) 14-8 14 - 4=10-4=6 8+7=15 8+6=14 8+8=16 -2 14 8-2=6 Invented Invented (using a fact I know) Addition and Subtraction Strategies, page 4, 2015 - 2016 MACC.2.NBT.2 Use place value understanding and properties of operations to add and subtract. The standard algorithm is introduced and taught in fourth grade: 4.NBT.4. Second and third grade students are encouraged to invent strategies when solving multi digit addition and subtraction problems for the following reasons. Place value concepts are enhanced. Students make fewer errors as they are focused on the number and number relationships. Less reteaching is necessary as they are inventing for themselves what makes sense. Mental computation and estimation are enhanced. Flexible thinking of number leads to strategies and this thinking is often faster than standard algorithms. Strategies serve students just as well as traditional algorithms on tests (including FCAT 2.0). Students who look at the meaning of numbers and use what they know to solve problems know and use more mathematics than those that follow a procedure.

(2006). Teaching Student-Centered Mathematics, Volume I, Boston: Pearson . Addition and Subtraction Strategies, page 6, 2015 - 2016 Strategies for BASIC Multiplication and Division Facts The development of strategies for multiplication and division is a critical area in the Mathematics Florida Standards (MAFS). By using and comparing a variety of solution strategies students build their understanding of the relationship between multiplication and division. The following information regarding multiplication and division strategies has been adapted from: Van de Walle, J.A., Lovin, L.H, Karp, K.S, & Bay-Williams, J.M. (2014). Teaching Student-Centered Mathematics, Volume II. Boston; Pearson. See chapters eight, nine, and eleven of this book for further clarification of multiplication and division strategies and. Multiplication Strategies Division Strategies Doubles Think Multiplication and then Apply a Known Multiplication Fact Fives Zeros and Ones Nifty Nines Using Known Facts to Derive Other Facts SPECIAL NOTES: The use of a problem-based approach and a focus on reasoning strategies are critical to developing mastery of the multiplication and related division facts. Thus, story problems should be used to develop reasoning strategies for basic fact mastery. BASIC Multiplication Fact Strategies Doubles These are facts with 2 as a factor and are equivalent to the addition doubles, so students should already know these. Students need experiences to help them realize that 2 x 8 is the same as double 8 (8 + 8). Fives These are facts that have 5 as a first or second factor. Mastery development ideas: Skip count by fives: 0, 5, 10, 15, 20 . . . Connect counting by fives with arrays that have 5 dots For example three rows is 3 x 5 Connect to counting minutes on the clock. Basic Multiplication and Division Fact Strategies, page 1 of 3, adapted from Van de Walle, J. A., Lovin, L. H, Karp, K. S, & Bay-Williams, J. M. (2014). Teaching Student-Centered Mathematics, Volume II. Boston; Pearson. Zeros and Ones These are facts that have at least one factor that is either 0 or 1. While these facts seem easy, they can be confusing to students because of rules for addition. For example, when zero is added to a number, it does not change the number (8 + 0 = 8). However, 8 x 0 = 0. Adding 1 to a number results in the next number, or one more (8 + 1 = 9), but a number multiplied by one does not change the number (8 x 1 = 8). The use of rules that are strictly procedural, such as “anything times zero is zero” should be avoided. Nifty Nines Facts with factors of 9 may be among the easiest to learn because of reasoning strategies and patterns. 9 x 8 is the same as 10 x 8 less one set of 8, or 80 – 8 = 72 The tens digit is always one less than the other factor (the factor other than 9) and the sum of the digits in the product is always 9. Therefore, for the fact 9 x 8, the tens digit is 7 and since the two digits in the product must add to 9 the ones digit is 2 and the product is 72. Patterns are not rules without reasons. Students should be challenged to understand why they work. Using Known Facts to Derive Other Facts Reasoning Strategies: Double and Double Again This applies to all facts with a factor of 4. For example, 4 x 6 is the same as 2 x 6 doubled. Note that for some facts such as 4 x 8, doubling the product may result in a difficult addition problem. For 4 x 8, a student knows 2 x 8 is 16, and then doubles 16. Doubling 16 is a difficult addition and simply adding 16 + 16 defeats the purpose of efficient reasoning. Students should use effective and efficient addition strategies such as, “I know 15 + 15 is 30 and 16 + 16 is 2 more, or 32.” Double and One More This works with facts that have 3 as one factor. For example, 3 x 6 is 2 x 6 and 6 more (12 + 6 = 18). Note that 3 x 8 and 3 x 9 result in challenging mental additions. Half then Double This applies to all facts with one even factor. For example, 6 x 8; half of 6 eights is 3 eights, 3 times 8 is 24, double 24 is 48. Close Fact strategy This involves adding one more set to a known fact. For example, think of 6 x 8 as 6 eights. Five eights is close and results in 40. Six eights is one more eight, or 48. Using 5 x 8 to figure out 6 x 8, the language “6 groups of eight” or “6 eights” can help students remember to add 8 more not 6 more. The Close Fact strategy can be used with any multiplication fact. It reinforces students’ number sense and relationships between numbers. Basic Multiplication and Division Fact Strategies, page 2 of 3, adapted from Van de Walle, J. A., Lovin, L. H, Karp, K. S, & Bay-Williams, J. M. (2014). Teaching Student-Centered Mathematics, Volume II. Boston; Pearson. BASIC Division Fact Strategies Reasoning Mastery of basic division facts is dependent on the inverse relationship of multiplication and division. For example, to solve 48 ÷ 6, we might naturally ask ourselves, “Six times what is 48?” The reasoning strategy is to (1) think multiplication, and then (2) apply a known multiplication fact. Near facts: 60 ÷ 8; mentally review a short sequence of multiplication facts comparing each product to 60: 6 x 8 = 48 (too low), 7 x 8 = 56 (close), 8 x 8 = 64 (too high). It must be 7, so that is 56 with 4 left over. NOTE: Division with remainders if much more prevalent in the real world than basic division facts that have no remainders. Students should be able to solve these near fact problems with reasonable speed. Basic Multiplication and Division Fact Strategies, page 3 of 3, adapted from Van de Walle, J. A., Lovin, L.

Brainstorm ways to solve this problem. What do you need to find out? Try two ways to solve the problem here. List words and phrases you need to include in your communication write up. Cognitive Complexity of Mathematics Items Low Complexity This category relies heavily on the recall and recognition of previously learned concepts and principles. Items typically specify what the student is to do, which is often to carry out come procedure that can be performed mechanically. It is not left to the student to come up with an original method or solution. The list below illustrates some, but not all, of the demands that items in the low complexity category might make: • Recall or recognize a fact, term, or property. • Identify appropriate units or tools for common measurements. • Compute a sum, difference, product, or quotient. • Recognize or construct an equivalent representation. • Perform a specified operation or procedure. • Evaluate a variable expression, given specific values for the variables. • Solve a one-step problem. • Retrieve information from a graph, table, or figure. • Perform a single-unit conversion. Moderate Complexity Items in the moderate complexity category involve more flexibility of thinking and choice among alternatives than do those in the low complexity category. They require a response that goes beyond the habitual, is not specified, and ordinarily has more than a single step. The student is expected to decide what to do, using informal methods of reasoning and problem solving strategies, and to bring together skill and knowledge from various domains. The list below illustrates some, but not all, of the demands that items of moderate complexity might make. • Solve a problem requiring multiple operations. • Solve a problem involving spatial visualization and/or reasoning. • Retrieve information from a graph, table, or figure and use it to solve a problem. • Compare figures or statements. • Determine a reasonable estimate. • Extend an algebraic or geometric pattern. • Provide a justification for steps in a solution process. • Formulate a routine problem, given data and conditions. • Represent a situation mathematically in more than one way. • Select and/or use different representations, depending on situation and purpose. High Complexity High complexity items make heavy demands on student thinking. Students must engage in more abstract reasoning, planning, analysis, judgment, and creative thought. The item requires that the student think in an abstract and sophisticated way. The list below illustrates some, but not all, of the demands that items in the high complexity category might make: • Perform a procedure having multiple steps and multiple decision points. • Describe how different representations can be used for different purposes. • Solve a non-routine problem (as determined by grade-level appropriateness). • Analyze similarities and differences between procedures and concepts. • Generalize an algebraic or geometric pattern. • Formulate an original problem, given a situation. • Solve a problem in more than one way. • Explain and justify a solution to a problem. • Describe, compare, and contrast solution methods. • Formulate a mathematical model for a complex situation. • Analyze or produce a deductive argument. • Provide a mathematical justification. NOTE: The complexity of an item is generally NOT dependent on the multiple-choice distractors. The options may affect the difficulty of the item, not the complexity of the item.
