Provide students with a key question.
Give them a few minutes to come up with a list of factors to help answer the question.
These are then added to the diagram (up to 8 factors can be added).
EITHER: This template is saved to the network, and each student opens it up and drags the factors into an order of priority
OR: The teacher leads a discussion / debate in which students are invited to come up to the interactive whiteboard and drag a factor into a position of priority and justify their choice to the class.
Finally, once a consensus has been reached, each student should write up the class verdict and explain the choice they made in as much detail as possible.
