What is it?

I adore probability, but its abstract nature means that it can be a tough topic for some learners to grasp. This resource helps to make the concept a little more concrete, enabling pupils to judge the validity of their answers through fun real-world scenarios. 

Under the guise of fairground fun, students must work together to calculate the percentage of winning eight different games. Questions range from sample spaces and tree diagrams, to dependent and independent events, and cover the majority of key skills at GCSE.

How can it be used?

Students tend to get the most out of this when working in small groups so I'd suggest setting it up as a carousel activity, allowing five minutes per section. Once their calculations are complete, learners can then take a chance at the fairground and see how their theoretical calculations match up to reality.

As an extension, why not challenge more-able students to design their own game, perhaps with a given probability of being won? If they are confident in completing this exercise, you know that their understanding is secure.
