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 lttMaths.com 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.
