Fascinating Fact:

Metres and centimetres. 1 m = 100 cm. The hall might be 12 m. Your book might be 20 cm.

In KS1 Maths, pupils compare length and height, estimate before measuring, and choose sensible units. We use rulers and metre sticks to read centimetres (cm) and metres (m) accurately.

  • Length: How long something is from end to end.
  • Height: How tall something is from bottom to top.
  • Unit (m or cm): The label we measure with, like metres (m) or centimetres (cm).

What is the difference between length and height?

Length is how long something is across, like a table. Height is how tall something is, like a door from floor to top.

Should I use centimetres or metres in Year 2?

Use centimetres for small objects (pencil, book) and metres for bigger things (classroom wall, corridor, playground distance).

How do you estimate length in KS1?

Look first and make a sensible guess, then measure with a ruler or metre stick to check. Estimating helps you choose the right unit.
