Product Description
Common Core Alignment:
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.
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.
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.

The composite shapes on these task cards can all be decomposed into rectangles and were designed for a third grade class. A few are basic rectangles, but they are more challenging because all the information is not given or they are finding rectangles with the same area or perimeter. Some cards include problem solving tasks and more challenging questions, so you can differentiate for students or groups.

This includes 16 task cards, a student recording sheet, and solutions. I also included some questions to promote higher-order thinking.
