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
• Instantly name the number of objects within small collections
• Use the counting sequence of ones flexibly
• Recognise number patterns
• Connect counting and numerals to quantities
##### Combining and separating quantities – MAO-WM-01, MAE-CSQ-01, MAE-CSQ-02
• Model additive relations and compare quantities
• Identify part–whole relationships in numbers up to 10

### Stage 1

##### Representing whole numbers – MAO-WM-01, MA1-RWN-01, MA1-RWN-02
