# Stage 2, Year A – Unit 12

This 2-week, Year A unit introduces the big idea that understanding relationships between the properties of 2D shapes helps visualise and organise spaces in the world.

Students are provided opportunities to:

• describe and compare features of two-dimensional shapes
• explore transformations through combining and splitting two-dimensional shapes
• learn how to estimate and find area using standard units of measurement.
