Why this why now
This unit focuses on the fact that, when one of the factors is 2, we can think about doubling. Pupils also relate the factor being doubled to being half of the product and use this to solve problems and identify missing factors. Exploring the inverse of multiplication will lead on to exploring division structures in the next unit.
Prior knowledge requirements
- Recall number facts and sequences
- Use place value understanding
- Apply basic operations in context

Multiplying by 2, doubling and halving (factors and products)
In this unit pupils will learn how multiplication with 2 as a factor relates to doubling and how we can see halving as the inverse of doubling, deriving the related halving fact from a known double.
