Mathematics – Stage 1 – Year B – Unit 39
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:
- recognise that flat surfaces of 3D objects can be named as 2D shapes
- use mathematical vocabulary to name, describe and compare the features of 2D shapes and 3D objects
- deconstruct and construct prisms and cubes
- see how 3D objects can look different depending on the point of view as it is manipulated
- make and use a calibrated measuring device to measure and compare internal volume
- measure and compare volume of various 3D objects.
