# Stage 3, mathematics, Year A – Unit 14

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

## 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 2-week unit, students are provided opportunities to:

• identify the appropriate unit and device to measure mass when solving problems
• recognise whole-number and decimal representations of mass
• use a variety of measuring devices to measure lengths and distances in different contexts, including perimeter.

### Syllabus focus and content groups

#### Represents numbers A – MAO-WM-01, MA3-RN-01, MA3-RN-02

• Decimals and percentages: Recognise that the place value system can be extended beyond hundredths
• Decimals and percentages: Compare order and represent decimals

#### Geometric measure A – MAO-WM-01, MA3-GM-02

• Length: Use metres and kilometres for length and distances
• Length: Measure lengths to find perimeters

#### Geometric measure B – MAO-WM-01, MA3-GM-02

• Length: Connect decimal representations to the metric system
• Length: Convert between common metric units of length

#### Non-spatial measure A – MAO-WM-01, MA3-NSM-01

• Mass: Choose appropriate units of measurement for mass
• Mass: Connect decimal representations to the metric system

#### Non-spatial measure B – MAO-WM-01, MA3-NSM-01

Mass: Convert between common metric units of mass
