The Human Galton Board
Last week we were booked in to do Human Markov Chains with several groups of school students, but it turned out there would be a lot fewer of them than we expected, and I didn't think Human Markov Chains would work very well with under 20 students. I still dearly wanted to do a moving maths activity, and I still wanted it to be about probability, but I wasn't sure what to do. Then, on the morning of the day the students were coming, I had an inspiration and quickly knocked together the Human Galton Board.
