Multi-age K–2, mathematics, Year A – Unit 09
Explore how collections of objects can be changed by adding more (combining) or taking some away (separating) 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.
In this unit, students will learn to:
- represent combining situations in different ways through the use of gesture, enactment, drawings, numbers and words
- use symbols to describe mathematical quantities, actions, and relationships in efficient ways
- understand that the order in which 2 quantities are combined does not change the result
- recognise that when 2 collections have the same total, they are described as ‘equivalent in value’. Words such as ‘equal’, ‘equivalent’, and ‘is the same as’ can also be used.
