Why this why now

This unit introduces non-unit fractions which are composed of more than one unit fraction. Pupils express non-unit fractions as a number of unit fractions, including one whole. They look at the fractions in different contexts, including placing them on a number line to mark a particular point in the number system. Pupils apply understanding of ordering unit fractions to compare other fractions with the same numerator and also compare non-unit fractions with the same denominator.

Prior knowledge requirements

  • Understand unit fractions and their representation
  • Use visual models (like number lines or shapes) to compare fractions
  • Recognise numerator and denominator and their roles
