# Use number facts to solve problems in measures and data contexts

I can use number facts to solve problems in measures and data contexts.

## Lesson details

### Key learning points

- Known addition and subtraction facts can be used to to help solve problems more efficiently.
- Drawing a bar model can help with understanding the problem.

### Common misconception

Children may have difficulty understanding the different ways in which 'difference' can be represented and the language associated with this.

Use a bar model to highlight the structure of the difference and create a range of problems, using different language, that could be solved using the same equation, e.g. problems which use both how many more and how many less/fewer.

### Keywords

Difference - The result of subtracting one number from another. How much one number differs from another.

Whole - All of something. Complete.

Part - A piece or a section of something.
