Mathematics – Multi-age – Year B – Unit 19
This two-week unit develops student knowledge, understanding and skills with three-dimensional objects, volume and internal 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:
- name, classify, compare and describe 2D shapes and 3D objects according to their features
- recognise that flat surfaces of 3D objects can be named as 2D shapes
- see how 3D objects can look different depending on student point of view
- measure and compare internal volume using uniform informal units, with no gaps or spaces to measure volume
- measure and compare volume of various 3D objects.
