Learning goals

  • We are learning to use estimation and rounding to check and explain calculations including transactions involving money.
  • We are learning to solve practical problems involving addition and multiplication including money problems, such as budgeting, using multiple strategies.
  • We are learning to use estimation and rounding to check the reasonableness of answers to calculations.
  • We are learning to use a range of strategies to solve multiplication and division where there is no remainder.
  • We are learning to calculate change to the nearest 5 cents and solve problems involving purchases.
  • We are learning to solve word problems by using number sentences involving multiplication or division where there is no remainder.
  • We are learning to solve problems involving purchases and calculate change to the nearest 5 cents, using both mental strategies and digital tools.
