Lesson Details

Key learning points

To compare non-unit fractions, the whole must be the same for each fraction.
When the numerators are the same, the greater the denominator, the smaller the fraction.
When the denominators are the same, the greater the numerator, the greater the fraction.

Common misconception

Pupils may struggle to compare fractions with the same numerator or denominator.

Encourage pupils to use fraction representations to help them visualise. Reference the size of the parts (same numerator, greater denominator means smaller parts) or how many there are (same denominator, greater numerator means more parts).
