# Stage 2, mathematics, Year B – Unit 33

This 2-week, Year B unit develops the big idea that multiplicative thinking involves flexible use of multiplication and division concepts, strategies and representations.

## Syllabus

Outcomes and content descriptors from 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.

In this 2-week unit, students are provided opportunities to:

• investigate and apply the use of multiples to determine unknown values
• use number properties to find related multiplication facts
• represent and solve word problems with number sentences involving multiplication or division.

### Syllabus focus area and content groups
