Mathematics – Stage 1 – Year A – Unit 17

This two-week unit introduces students to formal units of measurement and further develops student knowledge, understanding and skills of uniform informal units of measurement.

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:

  • compare, order and match using direct and indirect comparison with length, area, volume, and mass
  • consider how choice of measuring unit affects accuracy
  • learn why centimetres and metres are useful and how to measure with them.
