Jenga for revision

Jenga is a fun game which students like playing so I jumped onto eBay and bought five minisets at a couple of pounds each. I numbered each block and made a revision sheet with questions to match each number. The idea is that when they push the block out, they check the number on the sheet and answer the question, talk for 1 minute on the topic, list 10 things you can buy in that shop, list 10 colours etc. When I didn't have much time, I displayed this powerpoint instead of making up questions. Students could also write questions for the other team to answer.
