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. 17 Lessons 53, 54, 57, 58, 59, 61, 63, 78, 80 N/A Instruction: New Concept Lessons 62, 63, 64 Maintenance: Written Practice Lessons 62, 63, 64, 80, 99, 104 Instruction: New Concept Lessons 62, 63, 64, 79 Maintenance: Power Up Lessons 93, 103, 108 Written Practice Lessons 62, 63, 64, 65, 67, 68, 72, 73, 77, 79, 80, 88, 91, 92, 94, 97, 98, 99, 104, 105, 106, 107 Learning Stations Lessons 62, 63 Saxon Math Intermediate 3 ©2008 correlated to the Common Core States Standards for Mathematics (June 2010) Grade 3 Standard Descriptor Saxon Math Intermediate 3 Citations Italic references indicate foundational. 7c Use tiling to show in a concrete case that the area of a rectangle with wholenumber side lengths a and b + c is the sum of a x b and a x c. Use area models to represent the distributive property in mathematical reasoning. Instruction: New Concept Lesson 81 (see Teacher Edition Alternate Method and Math Background) This standard is further developed in Saxon Math Intermediate 4, Lesson 108 (see Student Edition and Teacher Edition). 7d Recognize area as additive. Find areas of rectilinear figures by decomposing them into non-overlapping rectangles and adding the areas of the nonoverlapping parts, applying this technique to solve real world problems. Instruction: New Concept Lesson 62 Maintenance: Written Practice Lesson 69 Performance Task 8 Test Day Activity 7 Geometric measurement: recognize perimeter as an attribute of plane figures and distinguish between linear and area measures. 8 Solve real world and mathematical problems involving perimeters of polygons, Instruction: including finding the perimeter given the side lengths, finding an unknown side New Concept length, and exhibiting rectangles with the same perimeter and different areas or with the same area and different perimeters.

Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories. Partition shapes into parts with equal areas. Express the area of each part as a unit fraction of the whole. For example, partition a shape into 4 parts with equal area, and describe the area of each part as 1/4 of the area of the shape.
