# Multi-age K–2, mathematics, Year B – Unit 06

This sample multi-age unit continues to explore the big idea 'equal means equivalent'.

## 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 with opportunities to:

• heft or place objects on either side of an equal-arm balance
• record the same as/equivalence using concrete materials
• use efficient addition and subtraction strategies to determine equality.
