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

This two-week unit develops students' knowledge, understanding and skills of making and using equal groups.

## 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:

• recognise, model and use equal and unequal groups
• share collections by forming equal groups
• use arrangements 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.
