**PART 4**

**Learning Intention**

- How can I compare the surface areas and volumes of cuboids?

**Pupil Task: **

- Draw on squared paper, labelled diagrams to represent the different faces of a cuboid.
- Work out their areas and hence find the total surface area of the cuboid.

**Teacher Guidance: **

- The suggestion here is that all the groups use the same number of cubes but create different cuboids with them.
- Once the children have drawn their (carefully)-labelled diagrams there can then be a whole-class discussion about the fact that all the cuboids have the same volume but they have different surface areas.
- This has interesting implications in real life situations such as heat loss or melting.
