Note for teachers: This worked well as a full 80 minute lesson – we had the full year group all together and in teams of 4-5. Each team is given the answer sheets (see word document). At the end of each round students swap papers and mark each others. We then collected papers in every 2 rounds to keep a running total of the score. We also made a “Maths Teachers Round” with 6-7 questions about the maths staff – fun trivia stuff, “Mr X once ate 12 hot dogs in a minute true or false” that kind of thing! We spent about 10 minutes on the pi memory challenge (we got some volunteers on stage – the best students got an extra 2 points for their team and a prize), With about 5-10 minutes to get everyone settled and in correct teams, and 10 minutes for the pi challenge, we got through about 4 rounds plus marking in 60 minutes – so there should be more than enough content here.
