In this unit, 'What needs to be measured determines the unit of measure', 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.

Representing whole numbers B – MAO-WM-01, MA1-RWN-01, MA1-RWN-02
