# Stage 2, mathematics, Year B – Unit 32

This 2-week, Year B unit develops the big idea that understanding relationships between properties of two-dimensional shapes helps visualise and organise spaces in the world.

## Syllabus

Syllabus outcomes 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.

Students are provided opportunities to:

• combine and split common shapes to create other common two-dimensional shapes
• transform shapes by reflecting, translating, and rotating
• measure and compare the areas of shapes using the grid structure and familiar metric units of area
