In this unit students will learn to:

  • recognising and representing numerals to 10
  • counting small collections of objects
  • identifying combinations of 2 numbers that add up to numbers less than 10
  • representing numbers 0-20 with drawings, numerals, symbols, and words
  • counting with one-to-one correspondence, recognising that the last number name represents the total number in the collection
  • using a ten-frame to represent smaller parts of a number
  • exposure to representing numbers on a rekenrek.
