Stage 2, mathematics, Year A – Unit 17
This 2-week unit develops the big idea that multiplicative thinking involves flexible use of multiplication and division concepts, strategies and representations.

Students are provided opportunities to:
- use patterns and array structures to support multiplicative thinking
- apply knowledge of multiplication to estimate, measure and compare area
- apply knowledge of multiplication to measure and compare volume using the row, column, layer structure.
Multiplicative relations A – MAO-WM-01, MA2-MR-01
- Generate and describe patterns
- Use arrays to establish multiplication facts from multiples of 2 and 4, 5 and 10
- Recall multiplication facts of 2 and 4, 5 and 10 and related division facts
Two-dimensional spatial structure A – MAO-WM-01, MA2-2DS-01, MA2-2DS-03
- 2D shapes: Compare and describe features of two-dimensional shapes
- Area: Use square centimetres to measure and estimate the areas of rectangles
Two-dimensional spatial structure B – MAO-WM-01, MA2-2DS-01, MA2-2DS-03
- Area: Measure the areas of shapes using the grid structure
- Area: Compare surfaces using familiar metric units of area
Three-dimensional spatial structure A – MAO-WM-01, MA2-3DS-01
- 3D objects: Make models of three-dimensional objects to compare and describe key features
- Volume: Compare objects using familiar metric units of volume
Three-dimensional spatial structure B – MAO-WM-01, MA2-3DS-01
3D objects: Connect three-dimensional objects and two-dimensional representations
