Multi-age K–2, mathematics, Year B – Unit 01
Collections of 10 are really useful– this unit introduces students to the big idea that collections of 10 are useful.
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.
In this unit students will learn to:
- notice, wonder, and ask questions about mathematical concepts around them
- count collections of objects by organising them and paying attention to the structure of groups
- combine and separate quantities
- recognise and explain how a collection of objects has been sorted
- describe two-dimensional spatial structures
- organise information into simple data displays and interpret these displays.
