CCSS.Math.Content.3.MD.C.7 - Relate area to the operations of multiplication and addition.

 

CCSS.Math.Content.3.MD.C.7.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.

 

CCSS.Math.Content.3.MD.C.7.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.

 

CCSS.Math.Content.3.MD.C.7.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 x b and a x c. Use area models to represent the distributive property in mathematical reasoning.

 

CCSS.Math.Content.3.MD.C.7.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.
