3
Domain:
Measurement and Data
Cluster:
Geometric measurement: understand concepts of area and relate area to multiplication and to addition.
Standard:
Relate area to the operations of multiplication and addition. 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.
