Lesson details

Key learning points

  1. Area can be measured in square metres.
  2. You write square metres as m²
  3. Fractions of square metres can be added to make whole square metres.

Common misconception

Pupils may believe that an area of one square metre has to be in the shape of a square.

Take two large pieces of paper, each one square metre, and fold them in half in different ways. Bring them together to form a square metre.

Keywords

  • Square metre - A square metre is a unit of measure equal to a square that is one metre on each side.

This practical lesson is very open-ended. There are many possibilities for making rectilinear shapes with a given square area. They could explore large areas with metre squared pieces of paper and also consider different fractions of square metres.
