In this unit students will learn to:
- explore how shapes can be made by joining (combining) and breaking apart (partitioning) existing shapes
- create new shapes by adding or removing sides and vertices (corners)
- recognise how two-dimensional (2D) shapes can be classified into different categories according to features
- create linear patterns with shapes that transform (slides and reflections)
- make designs with symmetry from reflection
- measure areas using uniform informal units
- use concrete materials to model dividing a whole length into halves and then subdividing into quarters
- model sharing and grouping collections of objects to represent division.
