About this worksheet

What students practice

  • Students find the area of a shape made of rectangles by adding the areas of its non-overlapping parts.
  • Students show that splitting a shape in different ways gives the same total area.
  • Students use a known total side length to find a missing side before finding the area.

How to use

Use after students can find the area of a rectangle by multiplying its side lengths. Have students color each rectangle part before they multiply, and let partners compare their garden designs in the last problem.
