Measures (Year 3)

In KS2 Maths, children will learn more about measures. In Year Three children will become familiar with grams and kilograms, litres and millilitres, and centimetres, metres and kilometres, and they should be able to choose the correct unit for different types of measurement, for example the use of centimetres, metres and kilometres to measure short, medium and long lengths respectively.

Millimetres, centimetres and metres are all types of measures. Measures can be used for the measurement of length (like centimetres, metres and kilometres), mass or weight (grams and kilograms) and liquid capacity (litres and millilitres). Measurements are a big part of everyday life. Imagine buying a new pair of trousers and shoes not knowing the size of your waist or feet!
