# Multi-age K–2, mathematics, Year A – Unit 13

Introduce students to the big idea of 'making and using equal groups' in this two-week, multi-age sample unit.

## 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.

In this unit, students will learn to:

• model and use equal groups of objects to represent multiplication
• use arrays to distinguish between the number of groups and the number in each group when describing collections of objects
• solve multiplication and division problems using objects, diagrams, images and actions.
