Work through the topic
Learn the method, follow the examples, then try the worksheet.
- 01
Circumference and area of circles
Use a circle’s radius to find its boundary length and the area it covers.
- 02
Perimeter/area of composite shapes
Split a composite region into familiar parts, then distinguish its area from its outside boundary.
- 03
Choosing and converting area units
Convert square units by applying the length conversion in both directions.
- 04
Cross-sections of prisms
Recognise the repeated cross-section that makes a solid a prism.
- 05
Prism volume and capacity
Find prism and cylinder volume, then express useful capacities in litres.
- 06
Mixed measurement applications
Plan a multi-step measurement solution and check that its units and assumptions fit the situation.
