CC.3.MD.5bA plane figure which can be covered without gaps or overlaps by n unit squares is said to have an area of n square units.
CC.3.MD.6Geometric measurement: understand concepts of area and relate area to multiplication and to addition. Measure areas by counting unit squares (square cm, square m, square in, square ft, and improvised units).
CC.3.MD.7Relate area to the operations of multiplication and addition.Skip Counting Mat Set
CC.3.MD.7aFind 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.Skip Counting Mat Set
CC.3.MD.7bMultiply 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.Skip Counting Mat Set
CC.3.MD.7cUse 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.
CC.3.MD.7dRecognize area as additive. Find areas of re
