# Mathematics – Multi-age – Year A – Unit 12

This two-week unit develops student knowledge, understanding, and skills in patterning.

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:

• understand that patterns repeat, and this repetition is referred to as the repeating core
• understand that some patterns can increase (grow) or decrease (shrink) by the same amount in each subsequent term
• develop an understanding of patterns in the place value system.

### Early Stage 1

##### Representing whole numbers A – MAO-WM-01, MAE-RWN-01, MA1-RWN-01, MAE-RWN-02, MA1-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, MA1-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, MA1-FG-01, MAE-FG-02
• Copy, continue and create pattern
##### Data – MAO-WM-01, MAE-DATA-01, MA1-DATA-01, MA1-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

##### Representing whole numbers A –
• 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
##### Representing whole numbers B –
• Use counting sequences of ones and tens flexibly
##### Combining and separating quantities A –
• Use advanced count-by-one strategies to solve addition and subtraction problems
• Recognise and recall numbers bonds up to ten
• Use flexible strategies to solve addition and subtraction problems
##### Forming groups A –
• Count in multiples using rhythmic and skip counting
• Use skip-counting patterns
##### Forming groups B –
• Model and use equal groups of objects to represent multiplication
• Represent and explain multiplication as the combining of equal groups
##### Data A –
• Ask questions and gather data
• Represent data with objects and drawings and describe the displays
##### Data B –
• Identify a question of interest and gather relevant data
• Create displays of data and interpret them
