Mathematics – Early Stage 1 – Unit 19

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

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:

  • name, describe and represent 2D shapes
  • explore familiar 3D objects by sorting, stacking, describing, and making representations
  • recognise that flat surfaces of 3D objects can be named as 2D shapes
  • measure and compare volume of various 3D objects
  • measure and compare internal volume (capacity) of various 3D objects.
