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:

  • model and use equal groups of objects to represent multiplication
  • use arrays 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.
