# Stage 2, mathematics, Year B – Unit 28

This 2-week, Year B unit develops the big idea that visual representation helps us to understand aspects of our world (chance and position).

## Syllabus

Syllabus outcomes from Mathematics K–10 Syllabus (2022) © NSW Education Standards Authority (NESA) for and on behalf of the Crown in right of the State of New South Wales, 2024.

Students are provided with opportunities to:

• use directional language to interpret and locate positions on a grid map while describing routes between points
• predict and describe possible outcomes from chance experiments
• use visualisation, language and multiple representations of position and chance concepts.

### Syllabus outcomes and content groups
