Unit fractions

Mathematics · Fractions · conceptual

Recognise, find, and write fractions of a discrete set of objects: unit fractions and non-unit fractions with small denominators

What mastery looks like

  • Find 1/4 of 12 objects by dividing into 4 equal groups
  • Find 3/4 of 12 objects
  • Write the fraction of a set that is shaded or selected

Check your understanding

If there are 15 books on a shelf, can Unit fractions work out how many two-thirds of them is — and check by grouping the books into three equal piles?
