Unit Summary
In this unit pupils will choose, use and compare appropriate standard units to estimate and measure length/height mass, capacity and temperature to the nearest appropriate unit.
Lesson Summary
You will learn to describe the size of a metre and a centimetre, and choose which unit might be best to measure different lengths.
Key Notes
- Length is measured in metres and centimetres.
- 1 cm is about the width of your thumbnail.
- 1 metre is about the height of the door handle.
Vocabulary To Learn
- Metres: A measure of length (about the height of a door handle).
- Centimetres: A measure of length (about the width of your thumbnail).

- Children may think that a metre and a centimetre are similar in length, due to the way they are presented in images that are not to scale.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.

2. Use this key word in a maths sentence and explain it clearly. 'Metres'
A measure of length (about the height of a door handle). Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Children may think that a metre and a centimetre are similar in length, due to the way they are presented in images that are not to scale. Correction: Allow children to explore practically and develop a sense of the length of one centimetre and one metre. Find familiar items to reference specific lengths e.g. our classroom door is about one metre wide.
