# Early Stage 1, mathematics – Unit 19

Develop students' skills with 2D shapes, 3D objects, volume, and internal volume (capacity) in this two-week unit.

## Syllabus

Syllabus outcomes and content descriptors from Mathematics K–10 Syllabus (2022) © NSW Education Standards Authority (NESA) for and on behalf of the Crown in right of the State of New South Wales, 2024.

In this unit – 'Objects can be sorted and classified in different ways', 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.
