In this unit, 'Objects can be sorted and classified in different ways', students are provided opportunities to:
- recognise that flat surfaces of 3D objects can be named as 2D shapes
- use mathematical vocabulary to name, describe and compare the features of 2D shapes and 3D objects
- deconstruct and construct prisms and cubes
- see how 3D objects can look different depending on the point of view as it is manipulated
- make and use a calibrated measuring device to measure and compare internal volume
- measure and compare volume of various 3D objects.
Representing whole numbers A – MAO-WM-01, MA1-RWN-01, MA1-RWN-02
- Represent numbers on a line
- Represent the structure of groups of ten in whole numbers
- Use counting sequences of ones with two-digit numbers and beyond
Representing whole numbers B – MAO-WM-01, MA1-RWN-01, MA1-RWN-02
- Use counting sequences of ones and tens flexibly
- Form, regroup and rename three-digit numbers
Two-dimensional spatial structure A – MAO-WM-01, MA1-2DS-01, MA1-2DS-02
2D shapes: Recognise and classify shapes using obvious features
Three-dimensional spatial structure A – MAO-WM-01, MA1-3DS-01, MA1-3DS-02
- 3D shapes: Recognise familiar three-dimensional objects
