# Multi-age K–2, mathematics, Year A – Unit 01

Develop students' knowledge, understanding, and skills of place value and working with collections of ten for mathematical thinking in this two-week, multi-age sample 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 will learn to:

• recognise, classify, and sort shapes using obvious features
• visualise, play with, and investigate the base 10 numerical system
• ask questions, gather, and represent data with objects and drawings.

## Syllabus focus area and content groups

### Early Stage 1

Representing whole numbers A – MAO-WM-01, MAE-RWN-01, MAE-RWN-02

• Instantly name the number of objects within small collections
• Use the counting sequence of ones flexibly

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

Two-dimensional spatial structure – MAO-WM-01, MAE-2DS-01, MAE-2DS-02

• 2D shapes: Sort, describe and name familiar shapes
• 2D shapes: Represent shapes

Data – MAO-WM-01, MAE-DATA-01

Organise objects into simple data displays and interpret the displays
