Mathematics – Multi-age – Year B – Unit 17

This two-week unit develops student knowledge, understanding and skills of measurement using informal and formal units.

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.

Students are provided opportunities to:

  • estimate, measure, compare and record a variety of attributes including length, area, volume and mass using informal units
  • estimate, measure and record length using formal units of metres and centimetres
  • recognise formal units of measurement ensure consistency and accuracy.
