# Mathematics – Stage 1 – Year B – Unit 33

This sample Stage 1 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.

Students are provided with opportunities to:

• identify between the number of groups and the number in each group when describing a collection of objects
• distribute a collection of objects equally into a given number of groups to determine how many in each group
• identify, form, rotate and name arrays using equal rows and equal columns to solve multiplication and division problems
• use counting strategies to find the total, for example, skip counting, counting on or double facts
• use various representation of diagrams, images or objects to model and solve multiplication and division problems.
