Stage 1, mathematics, Year B – Unit 23
What needs to be measured determines the unit of measurement – this unit develops student knowledge, understanding and skills of measurement.
In this unit, students will learn to:
- measure, record, compare and estimate a variety of attributes including length, area, volume, and mass using informal and formal units
- explore and connect mathematical measurement concepts
- apply mathematical measurement techniques to solve problems and communicate their thinking.
Representing whole numbers A – MAO-WM-01, MA1-RWN-01, MA1-RWN-02
- Use counting sequences of ones with two-digit numbers and beyond
- Continue and create number patterns
- Represent the structure of groups of ten in whole numbers
- Represent numbers on a line
Representing whole numbers B – MAO-WM-01, MA1-RWN-01, MA1-RWN-02
Use counting sequences of ones and tens flexibly
Combining and separating quantities A – MAO-WM-01, MA1-CSQ-01
- Use advanced count-by-one strategies to solve addition and subtraction problems

Forming groups B – MAO-WM-01, MA1-FG-01
Represent and explain multiplication as the combining of equal groups
Geometric measure A – MAO-WM-01, MA1-GM-01, MA1-GM-02, MA1-GM-03
Length: Compare lengths using uniform informal units
Geometric measure B – MAO-WM-01, MA1-GM-01, MA1-GM-02, MA1-GM-03
- Length: Compare and order lengths, using appropriate uniform informal units
- Length: Recognise and use formal units to measure the lengths of objects
Two-dimensional spatial structure A – MAO-WM-01, MA1-2DS-01, MA1-2DS-02
- Area: Indirectly compare area
