# Measure the area of flat shapes using square metres

You can measure the area of large shapes using square metres.

## Lesson details

### Key learning points

- Area can be measured in square metres.
- You write square metres as m²
- 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.
