# Stage 1, mathematics, Year B – Unit 28

This sample Stage 1 unit continues to explore the big idea 'what needs to be measured determines the unit of measurement'.

Students are provided with opportunities to:

• explore units of measurement
• describe lengths of objects
• describe fractions.

### Syllabus focus and content groups

Representing whole numbers A and B – MAO-WM-01, MA1-RWN-01, MA1-RWN-02

• Continue and create number patterns
• Represent numbers on a line
• Represent the structure of groups of ten in whole numbers
• Use counting sequences of ones and tens flexibly
• Form, regroup and rename three-digit numbers

Combining and separating quantities – MAO-WM-01, MA1-CSQ-01

• Recognise and recall number bonds up to ten

Forming groups A and B – MAO-WM-01, MA1-FG-01

• Count in multiples using rhythmic and skip counting
• Recognise and represent division
• Represent and explain multiplication as the combining of equal groups
• Model doubling and halving with fractions

Geometric Measure A – MAO-WM-01, MA1-GM-01, MA1-GM-02, MA1-GM-03

• Length: Measure the lengths of objects using appropriate uniform informal units
• Length: Subdivides the lengths to find halves and quarters
• Length: Compare and order lengths using uniform informal units

Two-dimensional spatial structure A and B – MAO-WM-01, MA1-2DS-01, MA1-2DS-02

• Area: Measure areas using uniform informal units
• 2D shapes: Identify and describe the orientation of shapes using quarter turns
• Area: Compare rectangular areas using uniform square units of an appropriate size in rows and columns

Three-dimensional spatial structure A and B – MAO-WM-01, MA1-3DS-01, MA1-3DS-02

• Volume: Measure and compare the internal volumes (capacities) of containers by filling
• Volume: Measure the internal volume (capacity) of containers by packing
• Volume: Construct volume using cubes
• Volume: Compare containers based on internal volume (capacity) by filling and packing
• Volume: Compare volumes by using uniform informal units

Non-spatial measure A and B – MAO-WM-01, MA1-NSM-01, MA1-NSM-02

• Time: Tell time to the half-hour
• Time: Describe duration using units of time
• Time: Tell time to the quarter hour using the language of ‘past’ and ‘to’
