# Multi-age K–2, mathematics, Year B – Unit 11

This two-week unit develops student knowledge, understanding, and skills of place value, number representation, and data.

## 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.

Students are provided with opportunities to:

• investigate the base 10 numerical system
• quantify, organise, and represent a variety of collections
• compare numbers through different representations
• collect and organise categorical data
• interpret data to ask questions and make informed decisions
• identify simple objects on a map and describe their position in relation to another object
• create and follow instructions along a path from the beginning to the end.

## Syllabus focus area and content groups

### Early Stage 1

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

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

Position: Describe position and movement of oneself

Data – MAO-WM-01, MAE-DATA-01

• Respond to questions, collect information and discuss possible outcomes of activities
• Organise objects into simple data displays and interpret the displays
