In this lesson, we will find out what the word 'double' means by making and spotting doubles.

In this lesson, we will learn about what 'half' means by practising halving amounts.

In this lesson, we will continue to practise halving.

In this lesson, we will look at the relationship between double and half.

This lesson is a revision lesson. We will revise one more, one less, counting in 2s, find missing numbers, counting, finding more and less, names of 2D and 3D shapes and doubling
