Lesson details

Key learning points

  1. To compare fractions with the same numerator, the whole must be the same.
  2. When the numerators are the same, the greater the denominator, the smaller the fraction.
  3. When the numerators are the same, the smaller the denominator, the larger / greater the fraction.

Common misconception

When a number is higher, its value is greater. Pupils may struggle to understand that as the denominator gets larger / greater, the size of the parts get smaller.

Show pupils lots of images, comparing fractions with the same numerator (e.g. one-fifth and one-third and then two-fifths and two-thirds). Highlight that even though the number of parts we have is the same, the size of those parts is different.

Keywords
