Mathematics – Multi-age – 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.

Mathematics K-2 Syllabus © 2022 NSW Education Standards Authority (NESA) for and on behalf of the Crown in right of the State of New South Wales.

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.
