# Mathematics – Multi-age – Year A – Unit 2

Patterns have something that repeats over and over and over again– this unit provides an opportunity to further develop students’ knowledge, skills and understanding of patterns.

In this unit students will learn to:

• describe repeating patterns made from shapes by referring to their distinguishing features such as colour, size, and shape
• understand that patterns have an element of repetition, meaning something repeats over and over and over again
• recognise that the element of repeat in a repeating pattern can sometimes be referred to as the repeating core
• use the pattern core to create their own patterns, extend the patterns of others and identify the missing elements within patterns
• develop an understanding that number bonds and dice structures are also forms of mathematical patterns that we come to trust
• understand that some patterns can grow (the pattern increases by the same amount in each subsequent term) and shrink (where the pattern decreases by the same amount in each subsequent term)
• instantly recognise (subitise) small collections of objects without counting
• identify, describe, and create patterns when counting forwards or backwards in twos, fives, and tens
• create, model, and recognise combinations for numbers up to 10
• apply knowledge of counting sequences to solve problems involving equal groups.

### Early Stage 1

##### Representing whole numbers A – MAO-WM-01, MAE-RWN-01, MAE-RWN-02
• 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
• Copy, continue and create pattern
• Investigate and form equal groups by sharing
• Record grouping and sharing
##### Two-dimensional spatial structure – MAO-WM-01, MAE-2DS-01, MAE-2DS-02
• 2D shapes: Sort, describe and name familiar shapes
• 2D shapes: Represent shapes
##### Data– MAO-WM-01, MAE-DATA-01, MAE-DATA-02
• Respond to questions, collect information and discuss possible outcomes of activities
• Organise objects into simple data displays and interpret the displays

### Stage 1

##### Combining and separating quantities – MA1-WM-01, MA1-CSQ-01, MA1-CSQ-02
• Recognise and recall numbers bonds up to ten
• Use knowledge of equality to solve related problems
##### Forming groups – MA1-WM-01, MA1-FG-01, MA1-FG-02
• Count in multiples using rhythmic and skip counting
• Use skip-counting patterns

• Represent and explain multiplication as the combining of equal groups
##### Two-dimensional spatial structure – MA1-WM-01, MA1-2DS-01, MA1-2DS-02
• 2D shapes: Recognise and classify shapes using obvious features
• Represent, combine and separate two-dimensional shapes
##### Data– MA1-WM-01, MA1-DATA-01, MA1-DATA-02
• Ask questions and gather data
• Represent data with objects and drawings and describe the displays
• Create displays of data and interpret them
