Area and Perimeter:
Learning Objectives:
3.MD.5 Recognize area as an attribute of plane figures and understand concepts of area measurement.
3.MD.6 Measure area by counting unit squares (square cm, square m, square in, square ft., and improvised units).
3.MD.7 Relate area to the operations of multiplication and addition.
3.MD.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.
