# Use repeated addition of a unit fraction to form a non-unit fraction

I can use repeated addition of a unit fraction to form a non-unit fraction.

# Use repeated addition of a unit fraction to form a non-unit fraction

I can use repeated addition of a unit fraction to form a non-unit fraction.

## Lesson details

### Key learning points

- Non-unit fractions are composed from unit fractions.
- Repeated addition of unit fractions forms non-unit fractions.
- A number line represents the repeated addition of unit fractions.

### Common misconception

Children may develop the misconception that unit fractions must be adjacent to be part of a repeated addition.

When using a number line, match it with another representation where possible in which the unit fractions aren't adjacent so children see that it is about the quantity of unit fractions rather than their position.
