# Multi-age K–2, mathematics, Year B – Unit 17

This two-week unit develops student knowledge, understanding and skills of measurement using informal and formal units.

## 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 opportunities to:

• estimate, measure, compare and record a variety of attributes including length, area, volume and mass using informal units
• estimate, measure and record length using formal units of metres and centimetres
• recognise formal units of measurement ensure consistency and accuracy.

## Syllabus focus and content groups

### Early Stage 1

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

• Use the counting sequence of ones flexibly
• Recognise number patterns
• Connect counting and numerals to quantities

Geometric measure – MAO-WM-01, MAE-GM-01, MAE-GM-02, MAE-GM-03

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

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

Area: Identify and compare area

Three-dimensional spatial structure – MAO-WM-01, MAE-3DS-01, MAE-3DS-02

• Volume: Compare internal volume by filling and packing
• Volume: Compare volume by building

Non-spatial measure – MAO-WM-01, MAE-NSM-01, MAE-NSM-02
