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.
Representing whole numbers – MAO-WM-01, MAE-RWN-01, MAE-RWN-02
