Stage 2, 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.
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
