Learning goals

  • We are learning to find a simple fraction of a quantity where the result is a whole number, e.g. 1/3 of a number is the same as dividing by 3.
  • We are learning to solve problems that require finding a familiar fraction, decimal or percentage of a quantity, including percentage discounts, choosing the best strategies.
  • We are learning to investigate and calculate percentage discounts of 10%, 25% and 50% on sale items, with and without digital technologies.
