Stage 1, mathematics, Year B – Unit 29
This sample Stage 1 unit continues to explore the big idea of combining and separating quantities.
Students are provided with opportunities to:
- understand that the order in which 2 quantities are combined does not change the result
- represent combining situations in different ways
- use different strategies, such as counting on and counting back.
Representing whole numbers A and B – MAO-WM-01, MA1-RWN-01, MA1-RWN-02
- Continue and create number patterns
- Represent numbers on a line
- Use counting sequences of ones with two-digit numbers and beyond
Combining and separating quantities – MAO-WM-01, MA1-CSQ-01
- Use advanced count-by-one strategies to solve addition and subtraction problems
- 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
- Use knowledge of equality to solve related problems
Forming groups A – MAO-WM-01, MA1-FG-01
- Count in multiples using rhythmic and skip counting
- Model and use equal groups of objects to represent multiplication
Forming groups B– MAO-WM-01, MA1-FG-01
Represent and explain multiplication as the combining of equal groups
Non-spatial Measure A – MAO-WM-01, MA1-NSM-01
Mass: Investigate mass using an equal-arm balance
Non-spatial Measure B – MAO-WM-01, MA1-NSM-01
Mass: Compare the masses of objects using an equal-arm balance
