Principles 2, 3
|
- How many cm3 (said "centimetres cubed") fit inside a cuboid which measures 3cm by 4cm by 5cm?
- There are 12 cubes on the front face.
- There are 5 'layers' of these. So in total there are 3X4X5 = 60 cubes = 60 cm2.
- Volume of a cuboid = base X height X depth. (Volume of a Pyramid may need to be discussed with some classes.)
|
Principle 4
|
| Volume of chocolate boxes
- Pair students. They need to identify the base, height and depth of each type of cuboid box, make measurements, and calculate the volume.
- Groups report back to check volume. Discuss how variations in measurements may cause slight variation in each group's answer. Discuss how each edge can be named the base depending on how you hold the box and this does not effect the resulting volume.

Principles 4, 5
|
Volume of other prisms
- Not all the boxes are cuboids. Many common 3D shapes are prisms. A prism is a 3D shape where the cross section of the shape and is the same size and shape as the end faces.

Vocab List
- Students scan their vocab list and look for words that they have seen in today's lesson. Can they improve their definition? Give students 3-4 minutes to discuss with partner. Students complete the After column with their new definition.
