  • 2: Read and write the fraction notation \(\frac{1}{2}\), \(\frac{1}{3}\) and \(\frac{1}{4}\), and relate this to a fraction of a length, shape or set of objects.
  • 3: Find half of numbers.
  • 4: Find \(\frac{1}{3}\) or \(\frac{1}{4}\) of a number.
  • 5: Find \(\frac{2}{4}\) and \(\frac{3}{4}\) of an object, shape, set of objects, length or quantity; recognise the equivalence of \(\frac{2}{4}\) and \(\frac{1}{2}\).
