This 2-week, Year B unit develops the big idea that the number system extends indefinitely to very large and very small numbers.

## 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 opportunities to:

• partition, rename, represent and order numbers up to 6-digits
• apply place value knowledge to recognise, name and order decimals to hundredths
• explore and apply the associative, distributive and inverse properties of multiplication and division to real-world number problems.
