# Early Stage 1, mathematics – Unit 11

Develop students' knowledge, understanding and skills with collections of 10 in this two-week unit.

## Syllabus

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.

In this unit – 'Collections of ten are really useful', students are provided with opportunities to:

• represent numbers in a variety of ways
• reason about the way numbers can be combined and separated
• use positional language both in a physical world context and in more abstract contexts
• compare the weight of different materials by hefting
• understand time in everyday contexts and tell time on analog and digital clocks
• explain their thinking so it makes sense to others.

### Syllabus focus and content groups

Representing whole number – MAO-WM-01, MAE-RWN-01, MAE-RWN-02

• Instantly name the number of objects within small collections

• Connect counting and numerals to quantities

Combining and separating quantities – MAO-WM-01, MAE-CSQ-01, MAE-CSQ-02

• Model additive relations and compare quantities
• Identify part–whole relationships in numbers up to 10

Geometric measure – MAO-WM-01, MAE-GM-01

Position: Describe position and movement of oneself

Non-spatial measure – MAO-WM-01, MAE-NSM-01, MAE-NSM-02
