Mathematics – 3–6 – Multi-age – Year A – Unit 3

This unit introduces the big idea that what needs to be measured determines the unit of measurement.

Mathematics K–10 Syllabus © 2023 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:

  • measure and compare lengths of objects using kilometres (Stage 3), metres, centimetres and millimetres
  • compare and describe features of two-dimensional shapes
  • measure, create and compare perimeters of two-dimensional shapes (Stage 3)
  • represent and read analog time (Stage 2)
  • represent and read digital, 12-hour and 24-hour time (Stage 3).
