Year 4 mathematics
In Year 3, children work with numbers into the thousands and use place value to add and subtract larger numbers. They build fluency with multiplication facts and the division facts that go with them, and they start measuring with metric units such as centimetres, kilograms and litres. They also explore fractions, shapes and angles, data displays and chance experiments.
