Multi-age 3–6, mathematics, Year B – Unit 01
This unit develops the big idea that our number system extends infinitely to very large and very small numbers.
Syllabus
Outcomes and content descriptors 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:
- partition, represent and order larger numbers
- apply place value to recognise, regroup and order whole and decimal numbers
- explore the link between multiplicative structures and place value to solve problems.
