This two-week unit develops student knowledge, understanding and skills of making and using equal groups.

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, model and use equal and unequal groups
• share collections by forming equal groups
• use arrangements to distinguish between the number of groups and the number in each group when describing collections of objects
• solve multiplication and division problems using objects, diagrams, images, and actions.

### 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
##### Forming groups – MAO-WM-01,MAE-FG-01, MA1-FG-01, MAE-FG-02
• Copy, continue and create patterns
• Investigate and form equal groups by sharing
• Record grouping and sharing

### Stage 1

##### Representing whole numbers B –
• Use counting sequences of ones and tens flexibly
• Form, regroup, and rename three-digit numbers
##### Combining and separating quantities A –
• Represent equality
##### Forming groups A –
• Count in multiples using rhythmic and skip counting
