New topic today with my friends in 10.2.2. Histograms. Histograms are an A/A* topic so I was expecting some blank faces. I got them. I think following Surds with Histograms is cruel and unnatural but they are year 10s and should be able to take it. Their science exam is over but still they moan.
Attempted a very cool (in my opinion) Excel spreadsheet with 9.2.2 in the computer room. Someone had figured out how to create a fully functioning roulette wheel on excel and I set them a task of working out the probability of winning, betting points and off they go. The trouble was that the macros were disabled and it didn't spin. Ooops. As I should have expected being 13 and 14 years old, they didn't really understand roulette either. Sigh.
