# Stage 1, mathematics, Year B – Unit 22

Patterns have something that repeats over and over and over again – this unit develops student knowledge, understanding and skills of two-dimensional shapes and their attributes and properties.

In this unit, students will learn to:

• sort collections using attributes and properties
• recognise, name and explore properties of two-dimensional shapes
• investigate repeating shape patterns that grow, shrink, radiate and are symmetrical
• investigate repeating number patterns that grow and shrink.

### Syllabus focus and content groups
