What mastery looks like

  • Given a shape divided into 5 equal parts, identify one shaded part as 1/5
  • Explain that 3/4 means 3 parts each of size 1/4
  • Draw a model showing 2/6 as 2 pieces of a whole cut into 6

Check your understanding

If you cut a pizza into 6 equal slices, can Fractions of a whole explain what 1/6 means — and then work out what 4/6 of the pizza looks like?
