Students are provided with opportunities to:

• heft or place objects on either side of an equal-arm balance
• record the same as/equivalence using concrete materials
• use efficient addition and subtraction strategies to determine equality

### Early Stage 1

##### Representing whole numbers – MAO-WM-01, MAE-RWN-01, MAE-RWN-02
• Use the counting sequence of ones flexibly
• 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
##### Non-spatial measure – MAO-WM-01, MAE-NSM-01, MAE-NSM-02
• Identify and compare mass using weight
