Mathematics – Multi-age – Year A – Unit 3

What needs to be measured determines the unit of measurement– this unit introduces students to measurement using direct and indirect comparison.

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.

In this unit students will learn to:

  • compare, order and match using direct comparison and informal units
  • estimate whether a measure is reasonable
  • consider how selection of measuring unit affects accuracy
  • explore conservation of length, area, volume, and mass.
