Area and volume unit conversions
Convert between related area and volume units by deriving and applying the square or cube of the linear conversion factor, including the relationship between cubic centimetres and litres. Use decimal notation up to three decimal places where appropriate; general linear-unit and time conversions are covered in Converting measurement units.
Lesson
Set out your lesson
“Area and volume unit conversions means practising the idea at the table with counters or paper models and one clear check. We will demo once, then your child tries.”
Bring to the table
- Two colours of counters
- Paper for ratio or percent notation
Extra for the adult
Worked example. 2 red and 3 blue is the ratio 2:3.
Optional challenge. For Area and volume unit conversions, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Area and volume unit conversions, not mastery.

Check understanding
- Explain from a 100-by-100 cm square why 1 m² = 10,000 cm², and use that factor in both directions
- Explain from a cube why 1 m³ = 1,000,000 cm³ rather than 100 cm³, and convert using the cubic factor
- Use 1000 cm³ = 1 litre to express 2500 cm³ as 2.5 litres, tracking the kind of unit
“If your child converts 3 m² to cm², can they explain why the factor is 100 × 100 rather than 100? Then ask them to explain how many cm³ make 1 m³ and to change 2500 cm³ into litres.”
