SAUSD Curriculum Map 2015-2016: Math 7 Math 7 These curriculum maps are designed to address CCSS Mathematics and Literacy outcomes. The overarching focus for all curriculum maps is building student’s content knowledge and literacy skills as they develop knowledge about the world. Each unit provides several weeks of instruction. Each unit also includes various assessments. Taken as a whole, this curriculum map is designed to give teachers recommendations and some concrete strategies to address the shifts required by CCSS. Instructional Shifts in Mathematics Focus: Focus strongly where the Standards focus Coherence: Think across grades, and link to major topics within grades Rigor: In major topics, pursue conceptual understanding, procedural skills and fluency, and application Focus requires that we significantly narrow and deepen the scope of content in each grade so that students experience concepts at a deeper level. Instruction engages students through cross-curricular concepts and application. Each unit focuses on implementation of the Math Practices in conjunction with math content. Effective instruction is framed by performance tasks that engage students and promote inquiry. The tasks are sequenced around a topic leading to the big idea and essential questions in order to provide a clear and explicit purpose for instruction. Coherence in our instruction supports students to make connections within and across grade levels. Problems and activities connect clusters and domains through the art of questioning. A purposeful sequence of lessons build meaning by moving from concrete to abstract, with new learning built upon prior knowledge and connections made to previous learning. Coherence promotes mathematical sense making. It is critical to think across grades and examine the progressions in the standards to ensure the development of major topics over time. The emphasis on problem solving, reasoning and proof, communication, representation, and connections require students to build comprehension of mathematical concepts, procedural fluency, and productive disposition. Rigor helps students to read various depths of knowledge by balancing conceptual understanding, procedural skills and fluency, and real-world applications with equal intensity. Conceptual understanding underpins fluency; fluency is practiced in contextual applications; and applications build conceptual understanding. These elements may be explicitly addressed separately or at other times combined. Students demonstrate deep conceptual understanding of core math concepts by applying them in new situations, as well as writing and speaking about their understanding. Students will make meaning of content outside of math by applying math concepts to real-world situations. Each unit contains a balance of challenging, multiple-step problems to teach new mathematics, and exercises to practice mathematical skills (Last updated May 18, 2015) 1 SAUSD Curriculum Map 2015-2016: Math 7 8 Standards for Mathematical Practice The Standards for Mathematical Practice describe varieties of expertise that mathematics educators at all levels should seek to develop in their students. These practices rest on important “processes and proficiencies” with longstanding importance in mathematics education. They describe how students should learn the content standards, helping them to build agency in math and become college and career ready. The Standards for Mathematical Practice are interwoven into every unit. Individual lessons may focus on one or more of the Math Practices, but every unit must include all eight: 1. Make sense of problems and persevere in solving them 2. Reason Abstractly and quantitatively 3. Construct viable arguments and critique the reasoning of others Mathematically proficient students start by explaining to themselves the meaning of a problem and looking for entry points to its solution. They analyze givens, constraints, relationships, and goals. They make conjectures about the form and meaning of the solution and plan a solution pathway rather than simply jumping into a solution attempt. They consider analogous problems, and try special cases and simpler forms of the original problem in order to gain insight into its solution. They monitor and evaluate their progress and change course if necessary. Older students might, depending on the context of the problem, transform algebraic expressions or change the viewing window on their graphing calculator to get the information they need. Mathematically proficient students can explain correspondences between equations, verbal descriptions, tables, and graphs or draw diagrams of important features and relationships, graph data, and search for regularity or trends. Younger students might rely on using concrete objects or pictures to help conceptualize and solve a problem. Mathematically proficient students check their answers to problems using a different method, and they continually ask themselves, "Does this make sense?" They can understand the approaches of others to solving complex problems and identify correspondences between different approaches. Mathematically proficient students make sense of quantities and their relationships in problem situations. They bring two complementary abilities to bear on problems involving quantitative relationships: the ability to decontextualize—to abstract a given situation and represent it symbolically and manipulate the representing symbols as if they have a life of their own, without necessarily attending to their referents—and the ability to contextualize, to pause as needed during the manipulation process in order to probe into the referents for the symbols involved. Quantitative reasoning entails habits of creating a coherent representation of the problem at hand; considering the units involved; attending to the meaning of quantities, not just how to compute them; and knowing and flexibly using different properties of operations and objects. Mathematically proficient students understand and use stated assumptions, definitions, and previously established results in constructing arguments. They make conjectures and build a logical progression of statements to explore the truth of their conjectures. They are able to analyze situations by breaking them into cases, and can recognize and use counterexamples. They justify their conclusions, communicate them to others, and respond to the arguments of others. They reason inductively about data, making plausible arguments that take into account the context from which the data arose. Mathematically proficient students are also able to compare the effectiveness of two plausible arguments, distinguish correct logic or reasoning from that which is flawed, and— if there is a flaw in an argument—explain what it is. Elementary students can construct arguments using concrete referents such as objects, drawings, diagrams, and actions. Such arguments can make sense and be correct, even though they are not generalized or made formal until later grades. Later, students learn to determine domains to which an argument applies. Students at all grades can listen or read the arguments of others, decide whether they make sense, and ask useful questions to clarify or improve the arguments. (Last updated May 18, 2015) 2 SAUSD Curriculum Map 2015-2016: Math 7 4. Model with mathematics 5. Use appropriate tools strategically 6. Attend to precision 7. Look for and make use of structure 8. Look for and express regularity in repeated reasoning Mathematically proficient students can apply the mathematics they know to solve problems arising in everyday life, society, and the workplace. In early grades, this might be as simple as writing an addition equation to describe a situation. In middle grades, a student might apply proportional reasoning to plan a school event or analyze a problem in the community. By high school, a student might use geometry to solve a design problem or use a function to describe how one quantity of interest depends on another. Mathematically proficient students who can apply what they know are comfortable making assumptions and approximations to simplify a complicated situation, realizing that these may need revision later. They are able to identify important quantities in a practical situation and map their relationships using such tools as diagrams, two-way tables, graphs, flowcharts and formulas. They can analyze those relationships mathematically to draw conclusions. They routinely interpret their mathematical results in the context of the situation and reflect on whether the results make sense, possibly improving the model if it has not served its purpose. Mathematically proficient students consider the available tools when solving a mathematical problem. These tools might include pencil and paper, concrete models, a ruler, a protractor, a calculator, a spreadsheet, a computer algebra system, a statistical package, or dynamic geometry software. Proficient students are sufficiently familiar with tools appropriate for their grade or course to make sound decisions about when each of these tools might be helpful, recognizing both the insight to be gained and their limitations. For example, mathematically proficient high school students analyze graphs of functions and solutions generated using a graphing calculator. They detect possible errors by strategically using estimation and other mathematical knowledge. When making mathematical models, they know that technology can enable them to visualize the results of varying assumptions, explore consequences, and compare predictions with data. Mathematically proficient students at various grade levels are able to identify relevant external mathematical resources, such as digital content located on a website, and use them to pose or solve problems. They are able to use technological tools to explore and deepen their understanding of concepts. Mathematically proficient students try to communicate precisely to others. They try to use clear definitions in discussion with others and in their own reasoning. They state the meaning of the symbols they choose, including using the equal sign consistently and appropriately. They are careful about specifying units of measure, and labeling axes to clarify the correspondence with quantities in a problem. They calculate accurately and efficiently, express numerical answers with a degree of precision appropriate for the problem context. In the elementary grades, students give carefully formulated explanations to each other. By the time they reach high school they have learned to examine claims and make explicit use of definitions. Mathematically proficient students look closely to discern a pattern or structure. Young students, for example, might notice that three and seven more is the same amount as seven and three more, or they may sort a collection of shapes according to how many sides the shapes have. Later, students will see 7 × 8 equals the well remembered 7 × 5 + 7 × 3, in preparation for learning about the distributive property. In the expression x2 + 9x + 14, older students can see the 14 as 2 × 7 and the 9 as 2 + 7. They recognize the significance of an existing line in a geometric figure and can use the strategy of drawing an auxiliary line for solving problems. They also can step back for an overview and shift perspective. They can see complicated things, such as some algebraic expressions, as single objects or as being composed of several objects. For example, they can see 5 3(x - y)2 as 5 minus a positive number times a square and use that to realize that its value cannot be more than 5 for any real numbers x and y. Mathematically proficient students notice if calculations are repeated, and look both for general methods and for shortcuts. Upper elementary students might notice when dividing 25 by 11 that they are repeating the same calculations over and over again, and conclude they have a repeating decimal. By paying attention to the calculation of slope as they repeatedly check whether points are on the line through (1, 2) with slope 3, middle school students might abstract the equation (y - 2)/(x - 1) = 3. Noticing the regularity in the way terms cancel when expanding (x - 1)(x + 1), (x - 1)(x2 + x + 1), and (x - 1)(x3 + x2 + x + 1) might lead them to the general formula for the sum of a geometric series. As they work to solve a problem, mathematically proficient students maintain oversight of the process, while attending to the details. They continually evaluate the reasonableness of their intermediate results.

ELs must have full access to high quality English language arts, mathematics, science, and social studies content, as well as other subjects, at the same time as they are progressing through the ELD level continuum. The CA ELD Standards are intended to support this dual endeavor by providing fewer, clearer, and higher standards. The ELD Standards are interwoven into every unit. Interacting in Meaningful Ways A. Collaborative (engagement in dialogue with others) 1. Exchanging information/ideas via oral communication and conversations B. Interpretive (comprehension and analysis of written and spoken texts) 5. Listening actively and asking/answering questions about what was heard 8. Analyzing how writers use vocabulary and other language resources C. Productive (creation of oral presentations and written texts) 9. Expressing information and ideas in oral presentations 11. Supporting opinions or justifying arguments and evaluating others’ opinions or arguments (Last updated May 18, 2015) 4 SAUSD Curriculum Map 2015-2016: Math 7 How to Read this Document The purpose of this document is to provide an overview of the progression of units of study within a particular grade level and subject describing what students will achieve by the end of the year. The work of Big Ideas and Essential Questions is to provide an overarching understanding of the mathematics structure that builds a foundation to support the rigor of subsequent grade levels. The Performance Task will assess student learning via complex mathematical situations. Each unit incorporates components of the SAUSD Theoretical Framework and the philosophy of Quality Teaching for English Learners (QTEL). Each of the math units of study highlights the Common Core instructional shifts for mathematics of focus, coherence, and rigor. The 8 Standards for Mathematical Practice are the key shifts in the pedagogy of the classroom. These 8 practices are to be interwoven throughout every lesson and taken into consideration during planning. These, along with the ELD Standards, are to be foundational to daily practice. First, read the Framework Description/Rationale paragraph, as well as the Common Core State Standards. This describes the purpose for the unit and the connections with previous and subsequent units. The units show the progression of units drawn from various domains. The timeline tells the length of each unit and when each unit should begin and end.

They are fluent in all positive rational number operations. Students have been introduced to ratio concepts and applications, concepts of negative rational numbers, absolute value, and all four quadrants of the coordinate plane. Students have a solid foundation for understanding area, surface area, and volume of geometric figures and have been introduced to statistical variability and distributions (Adapted from The Charles A. Dana 9 Center Mathematics Common Core Toolbox 2012). In grade seven instructional time should focus on four critical areas: (1) developing understanding of and applying proportional relationships, including percentages; (2) developing understanding of operations with rational numbers and working with expressions and linear equations; (3) solving problems involving scale drawings and informal geometric constructions and working with twoand three-dimensional shapes to solve problems involving area, surface area, and volume; and (4) drawing inferences about populations based on samples. (CCSSO 2010, Grade 7 Introduction). Students also work towards fluently solving equations of the form 𝑝𝑥 + 𝑞=𝑟 and (𝑥 + 𝑞)=𝑟.

This also provides further opportunities for practice and extension working with proportional reasoning and working with rational numbers. Framework Description: (7th Grade Framework, pages 28-31) In this section, students work towards developing an understanding of several concepts: Draw and constructing shapes-- (see 7th Grade Framework pg. 29 for brief details) Cross-sections of 3-D shapes Area and Circumference of Circles –focusing on understanding of the formulas and why they work (see 7th Grade Framework pgs. 30-31 for further explanation and examples). The focus should not be on memorization of formulas. Students focus on applying those formulas to other problems. Using facts about angles to find unknown angle measurements Dimensions of shapes --find the area, surface area, and volume of 2-D shapes and 3-D shapes composed of other shapes (see 7th Grade Framework pg. 31 for an example). Scale Drawings--Students solve problems involving scale drawing by applying their understanding of ratios and proportions. Compute actual lengths and areas and reproduced a scale drawing at a different scale. Students need to be able to determine that there are two important ratios with scale drawings: the ratios between two figures and the ratios within a single figure. Avoid using or defining similar shapes this will be done in 8th grade. (See 7th Grade Framework for more details pages 28-29) Academic Language Support Instructional Tool/Strategy Examples Preparing the Learner Key Vocabulary for Word Bank: Model the use of rulers, protractors, compass, and technology. Use strings to construct and name the figure. Double the strings size and construct the figure. Compare/calculate the ratios. Use the free software called GeoGebra Example: Draw an equilateral triangle with a side of 3 units using a compass and a straight edge. Use play-dough to create 3D shape and fishing line to cut into 2D shapes. Examine the cross-sections that result when 3D figures are split. Students describe how two or more objects are related in space (skew line) Activities: “Discovering Pi”: Students should “know” the formulas for area and circumference by being able to explain why the formula works and how the formula relates to area and circumference. Teachers should not give students any formulas or even the value of π until students discover it (see examples below). After students know the formulas, they should be able to apply their knowledge to solve problems: Students can also understand the relationship between circumference and area by tracing the circumference of a cylindrical can on patty paper, then measuring the diameter after folding the paper appropriately. Then, students can measure a string the same length as the diameter to realize that the string can go around the circumference approximately three and one-sixth times. This will lead them to understand that c=πd. Therefore, students discover π and the formula for circumference on their own. Students can cut circles into finer pie pieces (sectors) and arrange them side by side to create a parallelogram, which will create a length that is approximately πr and a height that is approximately r. This will give students the opportunity to come to the conclusion that the approximate area of this shape is πr2 Color and then cut out the angles of the triangles and put them together to see the relationship. Use patty paper to copy one of the vertical angles and apply it over the other angle to compare. Use 3D geometric shapes that students can hold and see the different shapes that compose a 3D figure. The use of graph paper and nets. For example, bring in realworld objects that students can use to solve for the area, volume, and or surface area (eg cereal boxes, shoe boxes, or cell phones) Earlier Grade: Acute Obtuse ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● Pi Circumference Area Compass Protractor Complementar y Supplementary Vertical Adjacent Surface Area Volume 2-Dimensional (2-D) 3-Dimensional (3-D) Slicing Polygons, triangles, quadrilaterals, cubes, right prisms, right rectangular pyramids (Last updated May 18, 2015) From 6th Grade: Area of right triangles, other triangles, special quadrilateral s, and polygons by composing into rectangles or decomposing into triangles, rectangles, and other shapes 21 SAUSD Curriculum Map 2015-2016: Math 7 Unit 6: Probability (3 weeks 04/11-04/29) Big Idea Essential Questions How can a model be used to predict the probability of an event occurring? How can you determine if a game of chance is fair? Unit Topics/Concepts The probability of a chance event occurring is between 0 and 1. 1. Understand that the probability of an event occurring can be represented as a fraction and understand the range in the probability relates to likelihood (closer to 1-more likely; closer to 0-less likely, and ½-neither likely or unlikely). 2. Collect data and approximate the probability of a chance event occurring. 3. Predict the relative frequency of an event based on a given probability. 4. Investigate both empirical and theoretical probability. Probability models can be used to find probabilities of events. 1.

Larger numbers indicate greater likelihood. A probability near 0 indicates an unlikely event, a probability around 1/2 indicates an event that is neither unlikely nor likely, and a probability near 1 indicates a likely event. 7.SP.6 Approximate the probability of a chance event 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.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.

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. 7.EE.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.

Students will utilize proportional reasoning in their use of samples to represent larger populations. The unit should be completed well before testing, allowing ample time before testing for SBAC prep and review, then enrichment, review, and/or preparation for the following year, after the SBAC. Framework Description: In this section, students work towards developing a deeper understanding of the following: Using samples to represent larger populations - applying understanding of proportions to develop this idea (see 7th Grade Framework Pg. 31-33 for further explanation and examples). Using measures of center and variability to compare two populations--building on their understanding of mean, median, mean, inter-quartile range, and mean absolute deviation students compare data from two populations (see 7th Grade Framework pgs. 33-34 for further explanation).

Recognize a statistical question as one that anticipates variability in the data related to the question 3. Recognize that a measure of center for a numerical data set summarizes all of its values with a single number, 4. Display numerical data in plots on a number line, including dot plots, histograms, and box plots. 5. Summarize numerical data sets in relation to their context 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.
