Multi-age K–2, mathematics, Year B – Unit 16
This two-week unit develops students' knowledge and skills in understanding different situations where addition, subtraction, multiplication and division can be used.
Syllabus
Syllabus outcomes and content descriptors from the Mathematics K–10 Syllabus (2022) © NSW Education Standards Authority (NESA) for and on behalf of the Crown in right of the State of New South Wales, 2024.
Students are provided opportunities to:
- investigate the 4 operations through problem solving
- explore the relationship between different operations and inverse operations
- engage in meaningful activities using repeated halving and doubling (Stage 1).
