Stage 1, mathematics, Year A – Unit 19

This two-week unit develops student knowledge, understanding and skills with two-dimensional (2D) shapes, three-dimensional (3D) objects and volume.

In this unit, 'Objects can be sorted and classified in different ways', students are provided opportunities to:

  • classify 2D shapes and 3D objects in different ways according to their features
  • recognise that flat surfaces of 3D objects can be named as 2D shapes
  • understand that 3D objects are named according to their features
  • see how 3D objects can look different depending on the perspective
  • measure internal volume using uniform informal units
  • compare and order internal volume based on size
  • recognise that 3D objects can have the same name but be a different size and appearance
  • compare 3D objects of a different appearance which have the same volume
  • understand that volume is recorded by referring to the number and type of uniform informal units used.

Representing whole numbers – 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 numbers on a line
  • Represent the structure of groups of ten in whole numbers
  • Form, regroup and rename three-digit numbers

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

Recognise and classify shapes using obvious features

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

  • 3D Objects: Recognise familiar three-dimensional objects
  • 3D Objects: Sort and describe three-dimensional objects
  • Volume: Measure and compare the internal volumes (capacities) of containers by filling
  • Volume: Measure the internal volume (capacity) of containers by packing
  • Volume: Construct volumes using cubes

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

  • 3D Objects: Describe the features of three-dimensional objects
  • Volume: Compare containers based on internal volume (capacity) by filling and packing
  • Volume: Compare volumes using uniform informal units
