Key learning points

When the whole is the same, the greater the number of equal parts, the smaller each equal part is.
When the whole is the same, the smaller the number of equal parts, the larger each equal part is.
When comparing unit fractions, the greater the denominator, the smaller the fraction.
When comparing unit fractions, the smaller the denominator, the larger the fraction.

Common misconception

Pupils may struggle to see that a unit fraction with a larger denominator is smaller than a unit fraction with a smaller denominator.

Pupils should be supported to visualise each fraction before moving on to interpreting abstract fraction notation. Encourage them to see the connection between the number of equal parts and the relative size of the fractions.
