Lesson details

Key learning points

To compare non-unit fractions, the whole must be the same for each fraction.
When you compare fractions with the same denominator, the greater the numerator the greater the fraction .
If the whole is not the same, you can not compare the fractions.

Common misconception

Pupils may try to compare fractions where the wholes are not the same.

It's important that pupils understand that for comparison of fractions the wholes must be the same. This lesson uses one example of comparing distances in miles versus distance in kilometres as well as comparing pizzas of different shape and size.

Keywords

Denominator - A denominator is the bottom number written in a fraction.
Numerator - A numerator is the top number written in a fraction.

Pupils compare fractions with the same denominator. Number lines will be useful for this and pupils may find it helpful to spend more time shading fraction strips of the same length to understand that when the denominator is the same, the fraction with the larger numerator is greater.
