Stage 2, mathematics, Year A – Unit 15
This 2-week, Year A unit develops the big idea that addition and subtraction problems can be solved using a variety of strategies.
In this 2-week unit, students are provided opportunities to:
- use the equals sign to mean 'the same as' to show equivalence, rather than to perform an operation
- select, represent and explain flexible strategies when solving addition and subtraction problems
- perform calculations with money, including finding change.
Representing numbers using place value A – MAO-WM-01, MA2-RN-01
- Whole numbers: Read, represent and order numbers to thousands
- Apply place value to partition and regroup numbers up to 4 digits
Representing numbers using place value B – MAO-WM-01, MA2-RN-01
Whole numbers: Apply place value to partition, regroup and rename numbers up to 6 digits
Additive relations A – MAO-WM-01, MA2-AR-01, MA2-AR-02
- Use the principle of equality
- Recognise and explain the connection between addition and subtraction
- Select strategies flexibly to solve addition and subtraction problems of up to 3 digits
- Represent money values in multiple ways
Additive relations B – MAO-WM-01, MA2-AR-01, MAR-AR-02
- Partition, rearrange and regroup numbers to at least 1000 to solve additive problems
