Mathematics – Multi-age – Year A – Unit 3
What needs to be measured determines the unit of measurement– this unit introduces students to measurement using direct and indirect comparison.

In this unit students will learn to:
- compare, order and match using direct comparison and informal units
- estimate whether a measure is reasonable
- consider how selection of measuring unit affects accuracy
- explore conservation of length, area, volume, and mass.
