  • Number: Fractions

This unit continues to look at non-unit fractions and introduces the use of repeated addition to represent the composition of non-unit fractions. Pupils develop their understanding of the role of the numerator and denominator to compare non-unit fractions with the same denominator and to add and subtract fractions with the same denominator. They develop the language of unitizing to build understanding that non-unit fractions are a number of unit fractions. This will prepare pupils for more formal calculation with fractions in the future.

  1. Use repeated addition of a unit fraction to form a non-unit fraction
  2. Use repeated addition of a unit fraction to form 1
  3. Add fractions with the same denominator
  4. Add on fractions with the same denominator
  5. Add fractions with the same denominator and generalise the rule
  6. Subtract fractions with the same denominator
  7. Add and subtract fractions with the same denominator in a range of contexts
  8. Explain that addition and subtraction of fractions are inverse operations
  9. Subtract fractions from a whole by converting the whole to a fraction
  10. Substitute a fraction representing a whole to solve subtraction problems
