Mathematics – Multi-age – Year A – Unit 4

Smaller numbers can be found hiding in bigger numbers – this unit provides opportunities to further develop student knowledge, understanding and skills of combinations of numbers that add up to a given number.

In this unit students will learn to:

  • count out a given number of objects from a larger collection
  • represent numbers as quantities using objects and numbers
  • create, model and recognise number combinations for numbers up to 10
  • count on from the largest number to find the total of 2 numbers
  • recognise and recall different combinations of 2 numbers that add up to a given number
  • identify patterns to find all combinations for a given number
  • use the bar model to represent parts of a number
  • identify and combine numbers which make doubles facts
  • describe combinations for numbers using words such as ‘more than’, and ‘less than’, and ‘double’
  • find smaller numbers inside larger numbers
  • identify near doubles by doubling the smaller number and adding one more or doubling the larger number and subtracting one less
  • recognise and record numbers in different representations including words, numerals and known structures such as dice, rekenreks and ten-frames.
Representing whole numbers – MAO-WM-01, MAE-RWN-01, MAE-RWN-02
