Learning goals

  • We are learning to recall addition facts to 20 and apply to related subtraction facts using a range of strategies.
  • We are learning to recall addition and subtraction facts to 20 and to develop mental strategies for larger numbers.
  • We are learning to use a range of mental strategies to solve simple addition and subtraction problems.
  • We are learning to solve problems involving modelling addition, subtraction, multiplication and division, using different strategies.
  • We are learning to solve multiplication problems using mental and written strategies and calculators to check our answers.
