Balloon questions
Students in 3 teams. Each team given a starter question to answer. Once they have the correct answer and I’ve checked it they can pop a balloon which contains the next question. The team with the most questions answer after a time limit (or when the baloons run out) is the winner.
[3 teams of 5, 15 baloons, 4 minute questions = 20 minute activity]
