Multi-age K–2, mathematics, Year A – Unit 03
Introduce students to measurement using direct and indirect comparison through this multi-age sample unit – What needs to be measured determines the unit 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 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.
