Start with a situation (students are given the amount Jo is paying for her current phone and her mobile phone usage over an average month). Students work in groups and put the statement cards in order from most to least important and decide on the best deal for Jo in the long and short term.

Thank you very much for this - should get the most reluctant mathematicians to get to work!
Great-just what I was looking for!
