Lesson details

Key learning points

When the numerator and denominator have the same value, the fraction is equal to one whole.
If the numerator is less than the denominator, the fraction is less than one whole.
Fractions that have numerators and denominators with the same values are also equal to each other.

Common misconception

Pupils may think that fractions with a higher value numerator are larger in size.

Show pupils images where fractions with the same numerators and denominators are equal in size (e.g. nine-ninths is equal to three-thirds).

Keywords

Denominator - A denominator is the bottom number written in a fraction.
Numerator - A numerator is the top number written in a fraction.
Whole - All of something. All of a group or number.

Pupils explore fractions that are equal to one whole or 1 Number lines combined with images representing fractions can help them make sense of this idea. Encourage pupils to count along the number line, seeing that when the numerator has the same value as the denominator, it is equal to 1
