Area & Perimeter

Area and perimeter stop being two formulas when you build them with your own hands. Your child colours squares on squared paper to make a shape with a given area, watches the perimeter being counted all the way round, and finds out that the same area can have a short edge or a long one.

What your child learns

  • Area as the number of squares inside a shape
  • Perimeter as the length all the way round
  • The same area can have different perimeters
  • Thinking ahead: long and thin, or close to a square

How to play

Tap a square to colour it, tap it again to clear it, or drag across several. The area counts as you go; from level 2 the edge is drawn and counted too. Tap Check when your shape is ready: it must be one piece, with squares touching side by side.

Levels

  1. Level 1Make a shape with the area Owlie asks for.
  2. Level 2Make a shape with a given perimeter.
  3. Level 3Both at once, then the same area with a longer perimeter.

A tip for parents

Draw shapes on squared paper from a school exercise book together. Which has more squares inside? Which has a longer fence round it?

Works on phones, tablets and computers, with nothing to install. No ads and no tracking.
