Mathematics – Stage 3 – Year A – Unit 3
This unit develops the big idea that what needs to be measured determines the unit of measurement.
Mathematics K–10 Syllabus © 2023 NSW Education Standards Authority (NESA) for and on behalf of the Crown in right of the State of New South Wales.
Students are provided with opportunities to:
- measure and compare lengths of objects using millimetres, centimetres, metres and kilometres
- measure, create and compare perimeters of two-dimensional shapes
- represent and read analog, digital, 12-hour and 24-hour time.
