• Количество слайдов: 61 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. The Big Maths KS 3 Pub Quiz You need to be in teams of 5 in your house colours. Maximum of 4 teams per house. Choose a team name and fill in your answer sheet Memorise pi Mental warm up. You have about 5 minutes to try and memorise as many digits of pi as possible. Then we will ask for 3 volunteers from each house.
