Mathematics – Multi-age – Year A – Unit 20

This two-week unit develops student knowledge, understanding and skills that problems can be solved and represented in different ways.

Mathematics K-2 Syllabus © 2022 NSW Education Standards Authority (NESA) for and on behalf of the Crown in right of the State of New South Wales.

Students are provided opportunities to:

  • solve modelled problems concretely, pictorially, and symbolically to help develop fluency
  • count and order a collection of items
  • place numbers accurately on a number line
  • use symbols to represent a story.
