Geometric measurement: understand concepts of area and relate area to multiplication and to addition. 14

7.Relate area to the operations of multiplication and addition. 11

- 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. 9
- 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. 9
- 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. 4 - 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. 4
