# Early Stage 1, mathematics – Unit 20

Develop students' knowledge, understanding and skills for solving problems related to number and time concepts 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, 'Problems can be solved and represented in different ways', students are provided opportunities to:

• solve problems by combining, separating and forming groups
• sequence and identify the duration of events using a range of methods
• read hour time on analog clocks
• explain and represent mathematical thinking in a variety of ways.

### Syllabus focus and content groups

Representing whole numbers – 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
• Recognise number patterns
• 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

Forming groups – MAO-WM-01, MAE-FG-01, MAE-FG-02
