Learning goals

  • We are learning to count collections of items (e.g. coins) and skip count by 5s or 10s to record how many in the collection.
  • We are learning to count in ones, twos, fives and tens, to and from 100.
  • We are learning to show that one- and two-digit numbers can be partitioned in different ways, such as partitioning two-digit numbers into tens and ones.
  • We are learning to count collections to 100 using place value groupings.
  • We are learning to add and subtract numbers within 20, using a variety of strategies, e.g. counting on, counting back, partitioning, subitising and part-part whole knowledge of numbers to 10 and to use the language of 'plus' and 'minus' in story problems.
  • We are learning to model problems involving addition and subtraction, including simple whole-dollar money problems, in practical role-play situations.
  • We are learning to use a range of strategies, to solve simple addition and subtraction problems.
  • 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 multiplication facts for twos and apply to related division facts using doubling and halving.
  • We are learning to explore number sequences by twos, threes, fives and tens from any starting point.
