# Multi-age K–2, mathematics, Year B – Unit 02

Patterns have something that repeats over and over and over again. This unit develops knowledge, understanding, and skills of two-dimensional shapes and their attributes and properties.

In this unit, students will learn to:

• sort collections using attributes and properties
• recognise, name, and explore properties of two-dimensional shapes
• investigate repeating shape patterns that grow, shrink, radiate, and are symmetrical
• investigate repeating number patterns that grow and shrink.

### Early Stage 1

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

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

Copy, continue and create patterns

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

Organise objects into simple data displays and interpret the displays

### Stage 1

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

• Use counting sequences of ones with two-digit numbers and beyond
• Continue and create number patterns
• Represent the structure of groups of ten in whole numbers
• Use counting sequences of ones and tens flexibly

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

• Use flexible strategies to solve addition and subtraction problems
• Form multiples of ten when adding and subtracting two-digit numbers

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

• 2D shapes: Recognise and classify shapes using obvious features
• 2D shapes: Represent, combine and separate two-dimensional shapes

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

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