# Stage 2 – Year A – Unit 9

This 2-week, Year A unit develops the big idea that what needs to be measured determines the unit of measurement.

In this 2-week unit, students are provided opportunities to:

• compare and describe features of three-dimensional objects by exploring models, sketches and diagrams
• construct and deconstruct nets of three-dimensional objects
• use formal units (litres and millilitres) to measure capacity and scaled instruments to measure and compare capacities.
