| Grouping | Whole class, independent and small group. |
| Resources | Fifty 1 cm or 2 cm cubes per student. Copy the activity on an overhead sheet, an overhead projector. |
| Lesson Notes | - Direct students to Model (a) on the overhead sheet and ask: Can you see every cube in this model? How long is the model? How wide is the model? How high is the model? How many cubes will you need to build the model? What is the volume of the model? Direct students build the model and record the number of cubes and the volume.
- Direct students to Model (b) and ask: Can you see every cube in this model? How long is the model? How wide is the model? How high is the model? How many cubes will you need to build the model? What is the volume of the model? Is this model going to be bigger than the first model? Why do you think that? Direct students build the model and record the number of cubes and the volume.
- Repeat for several more models.
- Direct students to independently complete the remaining tasks.
- Place students into small groups and ask: (Reflection) Have you all recorded the same volume for each model? Where there is disagreement rebuild the model and try and reach agreement.
- Provide the opportunity for students to share responses.
