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.

Multiplicative relations A – MAO-WM-01, MA2-MR-01

  • Generate and describe patterns
  • Use arrays to establish multiplication facts from multiples of 2 and 4, 5 and 10
  • Recall multiplication facts of 2 and 4, 5 and 10 and related division facts

Two-dimensional spatial structure A – MAO-WM-01, MA2-2DS-01, MA2-2DS-02, MA2-2DS-03

  • 2D shapes: Compare and describe features of two-dimensional shapes
  • 2D shapes: Transform shapes by reflecting, translating and rotating
