Domain - Measurement and Data
Cluster - Geometric measurement: understand concepts of area and relate area to multiplication and to addition.
[3.MD.C.5] - Recognize area as an attribute of plane figures and understand concepts of area measurement.
[3.MD.C.6] -
Measure areas by counting unit squares (square cm, square m, square in., square ft., and non-standard units).
[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.
[3.MD.D.8] -
Solve real-world and mathematical problems involving perimeters of polygons, including finding the perimeter given the side lengths, finding an unknown side length, and exhibiting rectangles with the same perimeter and different areas or with the same area and different perimeters.
