Print one answer sheet per team (plus a few spares) and one set of question cards. Arrange the question cards around the classroom / maths block / playground in the order of the reference numbers in the bottom left hand corner. Impress upon the students that this is not the order in which they will answer the questions.
Each team starts at a different question card – they write the answer from the top of that card in the top left corner of their answer sheet. They then solve the problem on the card and write their answer in the next empty circle. They then look for that answer at the head of another card and answer the question on that card next. So it continues until they get back to where they started.
