# Find one-half of a number

I can find one-half of a number and write this as an equation.

## Lesson details

### Key learning points

- To find one-half of a number you split it into 2 equal parts
- One-half of a number can be written as an equation using fraction notation.

### Common misconception

Children may try to make a group of 2 objects rather than share into 2 equal parts.

Use the stem sentence 'the whole group of _ has been divided into 2 equal parts and there are _ in each part' alongside concrete objects so that the children can experience dividing different numbers of objects into 2 equal parts.

### Keywords

One-half - One of two equal parts of a whole.
