## Lesson details

### Key learning points

- We can use known facts to help us find new facts efficiently.

### Common misconception

When solving problems, particularly in new contexts, children may revert to inefficient strategies as they are focusing on the problem rather than the number involved.

Encourage children to record the numbers involved on bar models, number lines or in equations, then focus on what they notice about the numbers.
