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 add and subtract one- and two-digit numbers, using a variety of strategies, e.g. partitioning, doubles, near doubles, bridging to 10 and rearranging and regrouping of numbers.
  • We are learning to solve problems by using number sentences for addition or subtraction.
  • We are learning to use a range of mental and written strategies to solve simple addition and subtraction problems.
  • We are learning to explore number sequences by twos, threes, fives and tens from any starting point.
  • We are learning to use a range of mental strategies to solve simple addition and subtraction problems.
