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.
