This sample Stage 1 unit continues to explore the big idea of combining and separating quantities.
Mathematics K-2 Syllabus © 2021 NSW Education Standards Authority (NESA) for and on behalf of the Crown in right of the State of New South Wales.
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
