Multi-age K–2, mathematics, Year A – Unit 04
Develop students' knowledge, understanding and skills in using combinations of numbers through this two-week, multi-age sample unit – Smaller numbers can be found hiding in bigger numbers.
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:
- count out a given number of objects from a larger collection
- represent numbers as quantities using objects and numbers
- create, model and recognise number combinations for numbers up to 10
- count on from the largest number to find the total of 2 numbers
- recognise and recall different combinations of 2 numbers that add up to a given number
- identify patterns to find all combinations for a given number
- use the bar model to represent parts of a number
- identify and combine numbers which make doubles facts
- describe combinations for numbers using words such as ‘more than’, and ‘less than’, and ‘double’
- find smaller numbers inside larger numbers
- identify near doubles by doubling the smaller number and adding one more or doubling the larger number and subtracting one less
- recognise and record numbers in different representations including words, numerals and known structures such as dice, rekenreks and ten-frames.
