# Early Stage 1, mathematics – Unit 03

Introduce students to the big idea ‘What you want to describe decides what unit of measure to use’ in this two-week unit.

## 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 measurement', students will learn to:

• recognise that the attribute you want to describe informs the unit of measure you use
• describe, compare, and order measurable attributes including length, area, volume and mass
• share their thinking when working with others to solve problems.

### Syllabus focus and content groups

Representing whole number – MAO-WM-01, MAE-RWN-01, MAE-RWN-02

• Instantly name the number of objects within small collections
• Connect counting and numerals to quantities

Geometric measure – MAO-WM-01, MAE-GM-02

Length: Use direct and indirect comparisons to decide which is longer

Two-dimensional spatial structure – MAO-WM-01, MAE-2DS-02

Area: Identify and compare area

Three-dimensional spatial structure – MAO-WM-01, MAE-2DS-02

Volume: Compare internal volume by filling and packing

Non-spatial structure – MAO-WM-01, MAE-NSM-01

Mass: Identify and compare mass using weight
