Mathematics – Early Stage 1 – Unit 5
New shapes can be made by joining (combining) or partitioning (breaking apart) existing shapes – develops students understanding of how new shapes can be made from existing shapes by exploring the attributes of shapes, and by using combination and partitioning.

In this unit students will learn to:
- two-dimensional (2D) shapes can be made by joining (combining) and breaking apart (partitioning) existing shapes
- shapes have attributes that are necessary for classification as that shape (features of triangles, circles, squares, rectangles)
- necessary attributes are called features
- shapes and objects can be halved in different ways
- new shapes can be created by adding or removing sides
- numbers, like shapes, have smaller numbers hiding inside of them (numbers 0 to 10)
