# Multi-age K–2, mathematics, Year A – Unit 07

Explore the big idea that 'data helps describe and wonder about the world' in this two-week, multi-age sample unit.

## Syllabus

Syllabus outcomes and content descriptors from the 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:

• collect and organise categorical data
• interpret data to make informed decisions
• identify and describe trends in data to predict the likelihood of outcomes
• use data as a powerful way to describe events in the world around us.
