Stage 1, mathematics, Year B – Unit 36
This two-week unit develops student knowledge and skills in understanding the many different situations where addition, subtraction, multiplication and division can be used.
Students are provided opportunities to:
- investigate the 4 operations through problem solving
- explore inverse operations
- engage in meaningful activities using repeated halving and doubling.
Representing whole numbers A – MAO-WM-01, MA1-RWN-01, MA1-RWN-02
- Represent numbers on a line
- Represent the structure of groups of ten in whole numbers
Representing whole numbers B – MAO-WM-01, MA1-RWN-01, MA1-RWN-02
- Use counting sequences of ones and tens flexibly
- Form, regroup, and rename three-digit numbers
Combining and separating quantities A – MAO-WM-01, MA1-CSQ-01
- Use advanced count-by-one strategies to solve addition and subtraction problems
- Recognise and recall number bonds up to ten
- Use flexible strategies to solve addition and subtraction problems
- Represent equality
Combining and separating quantities B – MAO-WM-01, MA1-CSQ-01
- Represent and reason about additive relations
