Mathematics – Multi-age – Year A – Unit 17
This two-week unit introduces students to formal units of measurement in length and further develops student knowledge, understanding and skills of uniform informal units of measurement.
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:
- compare, order and match using direct and indirect comparison with length, area, volume, and mass
- consider how choice of measuring unit affects accuracy
- learn why centimetres and metres are useful and how to measure with them.
