Number of Days: 18 Unit Goals Stage 1 Traditional: April 27 May 20; Track B: June 8 July 1 (17 days) Unit Description: In Unit 7 the students reason with shapes and their attributes, including perimeter and area. The standards in this unit strongly support one another because perimeter, like area, is an attribute of a shape. Materials: geoboards, graph paper, color tiles, Standards for Mathematical Practice Transfer Goals Students will be able to independently use their learning to SMP.1 Make sense of problems and Make sense of never-before-seen problems and persevere in solving them. persevere in solving them.

Look for and express regularity in repeated reasoning Standards for Mathematical Content [m] 3.MD.C 3.MD.7 Geometric measurement: understand concepts of area and relate area to multiplication and to addition. Relate area to the operations of multiplication and addition. a. Find the area of a rectangle with whole-number side lengths by tiling it, and show that the area is the same as would be found by multiplying the side lengths. b. Multiply side lengths to find areas of rectangles with whole-number side lengths in the context of solving real world and mathematical problems, and represent whole-number products as rectangular areas in mathematical reasoning. c. Use tiling to show in a concrete case that the area of a rectangle with whole-number side lengths a and b + c is the sum of a b and a c. Use area models to represent the distributive property in mathematical reasoning. d. Recognize area as additive. Find areas of rectilinear figures by decomposing them into non- overlapping rectangles and adding the areas of the non-overlapping parts, applying this technique to solve real world problems. [a] 3.MD.D Geometric measurement: recognize perimeter as an attribute of and distinguish between linear and area measures. 3.MD.8 Solve real world and mathematical problems involving perimeters of polygons, including finding the perimeter given the side lengths, finding an unknown side length, and exhibiting rectangles with the same perimeter and different areas or with the same area and different perimeters. [s] 3.G.A Reason with shapes and their attributes. 3.G.1 Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories. Key: [m] = major clusters; [s] = supporting clusters; [a] = additional clusters
Evidence of Learning Stage 2 Assessment Evidence Unit Assessment Students will complete selected response and constructed response items to indicate level of mastery/understanding of the unit standards as outlined in this guide. [m] 3.MD.C The student finds the area of a rectangle with whole-number side lengths. [a] 3.MD.D The student solves real world and mathematical problems requiring the student to find the perimeter of a polygon or using the perimeter (and the other side lengths), to find the length of one side. The student solves real world and mathematical problems requiring the student to construct two rectangles with the same perimeter and different areas, or with the same area and different perimeters. [s] 3.G.A The student identifies, draws, and classifies shapes (e.g., rhombuses, rectangles, and others) according to their attributes (e.g., having four sides) and recognizes that shared attributes can define a classification category. For selected content, students will need to Solve complex problems in pure and applied mathematics, making productive use of knowledge and problem solving strategies. Clearly and precisely construct viable arguments to support their own reasoning and critique the reasoning of others. Formative Assessment Opportunities Go Math!
