This two-week unit develops student knowledge, understanding and skills to solve mathematical problems using critical and strategic thinking.

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:

  • sequence events using a range of methods
  • solve time and duration problems using calendars and clocks
  • solve and record addition and subtraction problems using objects, diagrams and images
  • record answers to multiplication and division problems (including those with remainders) using drawings, words and numerals.
