# Multi-age 3–6, mathematics, Year B – Unit 09

This 2-week, Year B unit develops the big idea that what needs to be measured determines the unit of measurement.

## Syllabus

Syllabus outcomes 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.

Students are provided opportunities to:

• compare and describe features and properties of three-dimensional objects by making and exploring models, sketches and diagrams
• construct and draw models from given top, front and side views, using squared and isometric paper
• use formal units (litres and millilitres) to measure capacity and use scaled instruments to measure and compare capacities
• compare volumes of 2 or more objects by observing the change in water level when objects are submerged in a container of water
• recognise the equivalence of whole-number and decimal representations by measuring, comparing and ordering measurements of capacities of up to 3 decimal places.
