Two engaging activities to demonstrate and investigate inverse proportion in real life situations. Includes starters etc. There is a lesson plan, a PowerPoint and handout. There is plenty of differentiation included but it is mostly for middle / top sets (Yr9 / 10)

See for further ideas and resources about teaching mathematics.

    I really like the modelling opportunities in this lesson. There's something about the context that makes sense and may well appeal to those thinking about becoming nurses, doctors or business leaders. A great idea that goes further than the classic inverse proportion questions.

      Thanks. It was developed with colleagues in Seaham School of Technology. I particularly like the suprising way (for me anyway) how the graph turns out.
