Lesson details

Key learning points

  1. A non-unit fraction has a numerator greater than 1; it is composed of more than one unit fraction.
  2. We say, 'the whole has been divided into ___ equal parts, and I have ___ of them'.
  3. When writing fractions, the numerator is the top number showing the number of equal parts we have.
  4. The denominator is the bottom number showing the number of equal parts the whole has been divided into.

Common misconception

Pupils may count the number of equal parts that are shaded and write the numerator and then count the number that are not shaded and write the denominator.

Ensure that pupils count all of the equal parts to find the denominator. The denominator is the number of equal parts that make up whole. We encourage children to find, and then describe, the denominator before the numerator.
