The emphasis is to get away from the ‘here is some data work out the Mean, CF, IQR’ etc and more towards a contextual, problem solving direction. The PDF of the ‘Engaging Stats’ booklet which I recommend you have a look at. Pages 3-4 discuss in general terms the various issues. I suggest you use is the Crime Scene Evidence. This is simply based on a ‘suspects’ footprint and the following statistical inquiries that could be used to identify the culprit. The power point could be a useful way to introduce the task, either wholly or to ‘dip into’ when you want. You can then get a data set with your choice of sample size and age group. It was discussed that you may (upper end sets) wish to use and print off a larger set of data and then do your own sampling from that. Lower sets will probably just print off a smaller set sample for the class to work from.
