Multi-age K–2, mathematics, Year B – Unit 14

This two-week unit develops student knowledge, skills and understanding of measurement.

Syllabus

Syllabus outcomes and content descriptors from the Mathematics K–10 Syllabus (2022) © NSW Education Standards Authority (NESA) for and on behalf of the Crown in right of the State of New South Wales, 2024.

In this unit, 'What needs to be measured determines the unit of measure', students are provided opportunities to:

  • compare, order and match measurement attributes by using direct comparison and informal units
  • consider how the choice of measuring unit affects accuracy
  • explore conservation of length, area, internal volume (capacity) and volume and mass
  • explore, connect and communicate their thinking about mathematical measurement techniques.
