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:

  • use concrete materials, drawings, words, numerals and/or symbols to describe and explain mathematical operations
  • understand that the order in which 2 quantities are combined does not change the result
  • explore the inverse relation between addition and subtraction (Stage 1)
  • apply knowledge of related facts (number combinations to 10 and/or 20)
