About this chart

The same rectangle showing area (squares inside) and perimeter (sides around), with a tip for each.

What kids practice

Area is the amount of space inside a flat shape, measured in square units. Perimeter is the distance all the way around a shape, measured in units of length. Third graders find area by counting squares and then by multiplying length × width. They find perimeter by adding the side lengths, and learn that two shapes can have the same area but different perimeters.

Watch for

  • Mixing up area and perimeter. Area is inside; perimeter is around.
  • Adding only the two labeled sides of a rectangle instead of all four.
  • Writing area in plain units instead of square units.

It's free to print, as many copies as you need. See the full area and perimeter guide for 3rd grade.
