Learning goals

  • We are learning to solve practical problems involving natural and rational numbers and percentages in financial contexts.
  • We are learning to select and apply efficient mental and written strategies and digital technologies to solve problems involving addition, subtraction, multiplication and division with whole numbers.
  • 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 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.
