Mathematics – Multi-age – Year B – Unit 15
This two-week unit develops student knowledge and skills in understanding that a fraction can mean half a collection or half a measure.

Students are provided opportunities to:
- engage in meaningful activities using repeated halving to explore halves, quarters or eighths
- create and explore collections of objects that have or have not been divided into halves, quarters or eighths
- share objects into smaller groups and recognise if the number in each group is equal or not
- investigate division through sharing and grouping a collection, including leftovers.
Representing whole numbers – MAO-WM-01, MAE-RWN-01, MA1-RWN-01, MAE-RWN-02, MA1-RWN-02
- 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
Forming groups – MAO-WM-01, MAE-FG-01, MAE-FG-02, MA1-FG-01
- Investigate equal groups by sharing
- Record grouping and sharing
Geometric measure – MAO-WM-01, MAE-GM-03, MA1-GM-03
