Relay Race – Pie Charts goteachmaths.co.uk In this game students work in teams to answer questions on pieces of paper. Students should check their answers with the teacher (who can be anywhere in the room with their answer sheet). If students are correct they can collect the next numbered sheet (easily placed face-up on a desk at the front). If students are wrong they can be given 1 or more chances.
