# Stage 1, mathematics, Year B – Unit 34

This two-week sample Stage 1 unit develops students' knowledge, understanding and skills of measurement.

## Syllabus

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 unit 'What needs to be measured determines the unit of measure', students are provided opportunities to:

• measure, record, compare and estimate a variety of attributes including length, area, volume and mass using informal units
• explore and connect mathematical measurement concepts
• apply mathematical measurement techniques to solve investigations and communicate their thinking.
