2015-2016 Course Guide Geometry Critical Areas in Geometry The fundamental purpose of the course in Geometry is to formalize and extend students’ geometric experiences from the middle grades. Students explore more complex geometric situations and deepen their explanations of geometric relationships, moving towards formal mathematical arguments. Important differences exist between this Geometry course and the historical approach taken in Geometry classes. For example, transformations are emphasized early in this course. Close attention should be paid to the introductory content for the Geometry conceptual category found in the high school CCSS. The Mathematical Practice Standards apply throughout each course and, together with the content standards, prescribe that students experience mathematics as a coherent, useful, and logical subject that makes use of their ability to make sense of problem situations. The critical areas, organized into six units are as follows. (1) In previous grades, students were asked to draw triangles based on given measurements. They also have prior experience with rigid motions: translations, reflections, and rotations and have used these to develop notions about what it means for two objects to be congruent. In this unit, students establish triangle congruence criteria, based on analyses of rigid motions and formal constructions. They use triangle congruence as a familiar foundation for the development of formal proof. Students prove theorems—using a variety of formats—and solve problems about triangles, quadrilaterals, and other polygons. They apply reasoning to complete geometric constructions and explain why they work. (2) Students apply their earlier experience with dilations and proportional reasoning to build a formal understanding of similarity. They identify criteria for similarity of triangles, use similarity to solve problems, and apply similarity in right triangles to understand right triangle trigonometry, with particular attention to special right triangles and the Pythagorean Theorem. Students develop the Laws of Sines and Cosines in order to find missing measures of general (not necessarily right) triangles, building on students’ work with quadratic equations done in the first course. They are able to distinguish whether three given measures (angles or sides) define 0, 1, 2, or infinitely many triangles. (3) Students’ experience with two-dimensional and three-dimensional objects is extended to include informal explanations of circumference, area and volume formulas. Additionally, students apply their knowledge of twodimensional shapes to consider the shapes of cross-sections and the result of rotating a two-dimensional object about a line. (4) Building on their work with the Pythagorean theorem in 8th grade to find distances, students use a rectangular coordinate system to verify geometric relationships, including properties of special triangles and quadrilaterals and slopes of parallel and perpendicular lines, which relates back to work done in the first course. Students continue their study of quadratics by connecting the geometric and algebraic definitions of the parabola. (5) In this unit students prove basic theorems about circles, such as a tangent line is perpendicular to a radius, inscribed angle theorem, and theorems about chords, secants, and tangents dealing with segment lengths and angle measures. They study relationships among segments on chords, secants, and tangents as an application of similarity. In the Cartesian coordinate system, students use the distance formula to write the equation of a circle when given the radius and the coordinates of its center. Given an equation of a circle, they draw the graph in the coordinate plane, and apply techniques for solving quadratic equations, which relates back to work done in the first course, to determine intersections between lines and circles or parabolas and between two circles. (6) Building on probability concepts that began in the middle grades, students use the languages of set theory to expand their ability to compute and interpret theoretical and experimental probabilities for compound events, attending to mutually exclusive events, independent events, and conditional probability. Students should make use of geometric probability models wherever possible. They use probability to make informed decisions.

Mission To create an education system where all students achieve academic success, develop personal and civic responsibility, and achieve career and college readiness for the 21st century. Core Beliefs We believe: • • • • • • All students will learn and be successful. The achievement gap will be eliminated by ensuring every student is challenged to learn at, or above grade level. Effective teachers and principals, dedicated support staff, rigorous curriculum, measurable outcomes, ongoing monitoring and assessment, collaboration, professional development and a culture of continuous improvement will ensure classroom success for all students. Superior performance will be achieved through clear goals that set high expectations and standards for all students and employees. Family, school and community engagement will be required for student academic success. Leadership and passion, together with accountability and transparency, will be keys to reform and success. Philosophy of Mathematics Education • • • • Mathematical understandings of new concepts are taught through a planned learning progression through a coherent set of mathematics standards. Student learning of new content is facilitated through the mathematical shifts; focus coherence and rigor (conceptual understanding, application and procedural fluency). Students learn through the use of good tasks/questions, mathematical discussions and regular checks for understanding. All students should have the opportunity to learn and engage in the mathematics that prepares them for career and college. WCSD Mathematics Message Teachers in grades K-8, Algebra 1, Geometry and Algebra 2 are to teach to the Nevada Academic Content Standards for their grade level. We realize that students may have gaps in understanding and may need scaffolding to support conceptual development; yet we do not support a philosophy of only teaching procedurally to the gaps. Teachers may want to consider focusing intervention time on addressing concerns around the following domains; number sense, ratios and proportions and equations and expressions (this includes fractions in the intermediate grades and rational numbers in the grades 7-12). * Grade 6-8: Course Guides are designed to address topics within a unit of study and include reference to all of the NVACS-M for each grade. Students should have the opportunity to engage in all of the content standards for their grade and the amount of time spent on the topics and standards is recommended in the course guides. Teachers are expected to use both their adopted textbook and approved supplemental resources to meet the needs of their students. * Grade 9-12: Course Guides are designed to address topics within a unit of study. The NVACS-M provide the standards for Algebra 1, Geometry and Algebra 2. Students should have the opportunity to engage in all of the content standards for their course and the amount of time spent on the topics and standards is recommended in the course guides. Teachers are expected to use both their adopted textbook and approved supplemental resources to meet the needs of their students Fourth year courses have been revised to engage students in the fourth year standards from the NVACS-M and topics that best address the intent of the course. * Grading recommendations are made for mathematics courses in grades 6-12. See course guide. * The Curriculum and Instruction department have many professional development opportunities for teachers currently posted on Professional Learning Café. Please feel to contact Vicki Collaro [email protected] with questions regarding interpretations of the standards or course guides and [email protected] for assessment particulars. Assessment Philosophy • Assessment is the continuous process of collecting information to make decisions about teaching and learning • A balanced assessment program is essential for determining and reporting the learning needs, progress, and achievement of students at the state, district, and classroom levels • The most impactful assessment comes from a teacher with well-planned units, lessons, and multiple strategies designed to elicit evidence of student learning • Assessments must begin with clear purpose, targets and design to provide information from which valid inferences can be made • Assessment use must always adhere to the intended purpose of the assessment • Practicing for an assessment by focusing on specific items and tested skills does not promote lasting student achievement, and the assessment itself should never be the learning target. • Formative Assessment Processes including close, purposeful observation provide valuable data integral to student learning at every grade level • Self-assessment and self-monitoring activities enhance student self-efficacy • Clear, specific, and timely feedback must accompany assessment On the following pages are guidelines and information for planning instruction around the Common Core State Standards. Teachers should look for opportunities to incorporate the Mathematical Practices from the Common Core State Standards (CCSS) into planning and instruction where appropriate. "What students can learn at any particular grade level depends upon what they have learned before" (CCSS Introduction, p. 5). Teachers are encouraged to communicate with other grade levels and align practices and goals to support vertical transitions. Review the CCSS critical areas of focus for grades 6-12 to assist in planning short and long-range goals for student learning and strengthening teaching of the Mathematics Standards. Students should engage in 60 minutes of daily math instruction (minimum). Recommendations for 6-12 Grading in Mathematics Note: Grading recommendations were established to provide those that need more specific direction somewhere to start. The importance of the recommendations is that consistency is established at a school site or between a feeder middle school and the high school. The PLC group should decide on more specific grading policies for their school but should be in line with the recommendations here. 1. Grading at any level should be consistent within the building for like grades and courses. 2. Assignments are assigned and are completed by the students on their own time or in class with assistance. Individual performance on projects may be included in this category. 3. Quizzes/In Class Checks are evaluations of what the students know but could be used to inform instruction or offer additional assistance to a student. Students may have multiple attempts to get these points but each attempt needs to be completed by the individual without assistance. 4. Assessments are to determine what the students have learned and are summative in nature. These are individual performance measures and should be monitored assessments. Students may have the opportunity to take a retake. Grades recorded in assessment should reflect what the students know. Caution should be given to practices that would inflate test grades. 6-12 Math Courses Grading Recommendations Math 6, Math 7, Math 8, Math 7-8 Grading Recommendations: • Assignments (independent work, projects, group work) – 10-15% • Final – 10% (2015-16) • Quizzes (monitored in class checks, individual performance) – 20-30% • Assessments/Exams (individual performance) – 40-55% Algebra 1, Geometry, Formal, Algebra 2, and non-honors 4th year courses Grading Recommendations: • Assignments (independent work, projects, group work) – 10-15% • Final – 15% (2015-16) • Quizzes (monitored in class checks, monitored individual performance) – 10-20% • Assessments/Exams (monitored individual performance) – 45-60% Honors Mathematics Courses Grading Recommendations: • Assignments (independent work, projects, group work) – 0-10% • Final – 15-20% (2015-16) • Quizzes (monitored in class checks, monitored individual performance) – 10-20% • Assessments/Exams (monitored individual performance) – 60-70% WCSD Recommended Pathways to Advanced Mathematics Grade 7 Options Grade 8 Options Grade 9 Options Grade 10 Options Grade 11 Options Grade 12 Options Trigonometry Pre-Calculus Geometry ** Math 7 Math 8 Algebra 2** Prob/Stat Discrete Algebra 1 Geometry and Algebra 2 ** Adv.

These practices rest on important “processes and proficiencies” with longstanding importance in mathematics education. The first of these are the NCTM process standards of problem solving, reasoning and proof, communication, representation, and connections. The second are the strands of mathematical proficiency specified in the National Research Council’s report Adding It Up: adaptive reasoning, strategic competence, conceptual understanding (comprehension of mathematical concepts, operations and relations), procedural fluency (skill in carrying out procedures flexibly, accurately, efficiently and appropriately), and productive disposition (habitual inclination to see mathematics as sensible, useful, and worthwhile, coupled with a belief in diligence and one’s own efficacy). 1. Make sense of problems and persevere in solving them. 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. 2. Reason abstractly and quantitatively. 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. 3. Construct viable arguments and critique the reasoning of others. 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. 4. Model with mathematics. 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. Mathematical Practices 5. Use appropriate tools strategically. 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. 6. Attend to precision. 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. 7. Look for and make use of structure. 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 equals7 × 5 + 7 × 3, in preparation for learning about the distributive property. In the expression + 9 + 14, older students can see the 14as2 × 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(– ) 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. 8. Look for and express regularity in repeated reasoning. 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 (– 2)/(– 1) = 3. Noticing the regularity in the way terms cancel when expanding (– 1)( + 1), (– 1)( + + 1), and (– 1)( + + + 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. Connecting the Standards for Mathematical Practice to the Standards for Mathematical Content The Standards for Mathematical Practice describe ways in which developing student practitioners of the discipline of mathematics increasingly ought to engage with the subject matter as they grow in mathematical maturity and expertise throughout the elementary, middle and high school years. Designers of curricula, assessments, and professional development should all attend to the need to connect the mathematical practices to mathematical content in mathematics instruction. The Standards for Mathematical Content are a balanced combination of procedure and understanding. Expectations that begin with the word “understand” are often especially good opportunities to connect the practices to the content. Students who lack understanding of a topic may rely on procedures too heavily. Without a flexible base from which to work, they may be less likely to consider analogous problems, represent problems coherently, justify conclusions, apply the mathematics to practical situations, use technology mindfully to work with the mathematics, explain the mathematics accurately to other students, step back for an overview, or deviate from a known procedure to find a shortcut. In short, a lack of understanding effectively prevents a student from engaging in the mathematical practices. In this respect, those content standards which set an expectation of understanding are potential “points of intersection” between the Standards for Mathematical Content and the Standards for Mathematical Practice. These points of intersection are intended to be weighted toward central and generative concepts in the school mathematics curriculum that most merit the time, resources, innovative energies, and focus necessary to qualitatively improve the curriculum, instruction, assessment, professional development, and student achievement in mathematics.
