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

This two-week unit develops student knowledge, skills and understanding about repeating patterns, arrays and different ways to present and communicate about data.

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:

• recognise, name, create and extend various patterns
• identify that repeating patterns have a core that repeats over and over and over again
• identify, describe, organise and compare a variety of repeating patterns and arrays
• communicate their understanding and thinking as they create and explore various patterns and arrays
• select appropriate methods to display and interpret data.

### Early Stage 1

##### Representing whole numbers – 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, 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 patterns

### 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
• Form, regroup, and rename three-digit numbers
##### Forming groups A –
• Count in multiples using rhythmic and skip counting
• Use skip counting patterns
• Model and use equal groups of objects to represent multiplication
##### Forming groups B –
• 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 –
• Create displays of data and interpret them
