| Lesson Notes |
- Direct students to the Investigation and ask: What do you need to find out? Is there only one answer to this problem?
- Why do you think that? What measures do you think you will need to make? Direct students to begin planning their investigation by drawing a diagram to show how they will solve this problem.
- (Reflection) Bring students together on several occasions to share developing ideas.
- Direct students with completed plans to carry out their working.
- Move around the class and ask: (Reflection) What do you need to find out? Have you been given all the information you need in the problem? What further information did you need to collect? Can you show me the measures you will make? Will all our boxes be the same size? Will all our box shapes be the same shape? If you change the shape of the Corn Flakes in the plastic bag will that change the amount of cardboard you will need? What shape would you make the box so that it uses the least amount of cardboard? ...
- Provide students with the opportunity to share and compare responses. Ask: Are the volumes we have measured all the same or very similar? Why is that? How many different box shapes have we found that have the same or very similar volume? Which of our box designs uses the least cardboard? Most cardboard?
