# Mathematics – Early Stage 1 – Unit 1

Attributes can be used to sort objects  – Sample unit to support implementation of the Mathematics K-2 Syllabus. In this unit, students are introduced to sorting objects using attributes.

Mathematics K-2 Syllabus © 2021 NSW Education Standards Authority (NESA) for and on behalf of the Crown in right of the State of New South Wales.

In this unit students will learn to:

• combine and separate quantities
• recognise and explain how a group of shapes has been sorted
• describe two-dimensional spatial structures
• organise objects into simple data displays and interpret these displays.

## Syllabus focus and content group

### Early Stage 1

##### 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
• Use the counting sequence of ones flexibly
• Identify the number before as ‘one less’ and the number after as ‘one more’ than a given number
##### Combining and separating quantities – MAO-WM-01, MAE-CSQ-01, MAE-CSQ-02
• Identify part–whole relationships in numbers up to 10
• Model additive relations and compare quantities
##### Two-dimensional spatial structure – MAO-WM-01, MAE-2DS-01
• 2D shapes: Sort, describe and name familiar shapes
• 2D shapes: Represent shapes
##### 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
