# Stage 1, mathematics, Year A – Unit 01

Develop students' knowledge, understanding, and skills with place value, and how attributes can be used to sort objects in 'Collections of ten are really useful'.

## 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, and investigate the base 10 numerical system
• ask questions, gather data, and represent data with objects and drawings.

### Syllabus focus and content groups

Representing whole numbers A – MAO-WM-01, MA1-RWN-01, MA1-RWN-02

• Use counting sequences of ones with two-digit numbers and beyond
• Represent the structure of groups of ten in whole numbers

Combining and separating quantities A – MAO-WM-01, MA1-CSQ-01

• Recognise and recall number bonds up to ten
• Use flexible strategies to solve addition and subtraction problems
• Represent equality

Combining and separating quantities B – MAO-WM-01, MA1-CSQ-01

• Form multiples of ten when adding and subtracting two-digit numbers
• Use knowledge of equality to solve related problems

Two-dimensional spatial structure A – MAO-WM-01, MA1-2DS-01, MA1-2DS-02

2D shapes: Recognise and classify shapes using obvious features

Two-dimensional spatial structure B – MAO-WM-01, MA1-2DS-01, MA1-2DS-02

2D shapes: Represent, combine and separate two-dimensional shapes

Data A – MAO-WM-01, MA1-DATA-01, MA1-DATA-02

• Ask questions and gather data
• Represent data with objects and drawings and describe the displays

Data B – MAO-WM-01, MA1-DATA-01, MA1-DATA-02

• Identify a question of interest and gather relevant data
• Create displays of data and interpret them
