The Nrich interactivity offers an ideal context in which to observe the "messy" randomness of results after a small number of experiments, and the predictability of results after a large number of trials. The problem also offers a good starting point for considering different probability distributions and their features, which could be followed up with the tasks Which List is Which and Data Matching.

This Nrich activity would be a good start to, or could follow on from, work on finding percentages of quantities. In whichever context it is used, it will provide a good assessment opportunity for you to find out what your pupils understand well and what they have difficulties with.

This Nrich problem challenges learners to interpret data carefully and to search for all the information that there is implicit in any graphical representation. The question encourages them to contrast different ways of representing similar data and helps to make explicit their interpretation of what the data represents in order to solve the problem.
