Mathematics – Stage 1 – Year A – Unit 14
This two-week sample Stage 1 unit introduces students to measurement using uniform informal units.
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 informal units of measurement
- estimate whether a measurement is reasonable
- consider how selection of measuring unit affects accuracy
- explore conservation of length, area, volume and mass.
