1. Give the students small pieces of paper. Tell the students to write down vocabulary that you want them to revise or you can get them to write down nouns etc
2. Students write down the words and put them in a container. Put the class into teams.
3. Set a timer for 2 or 3 minutes or however long you wish. The teams take turns. Students take words from the container and explain them to their team. When the team says the correct word, the next student takes their turn and moves onto the next word. The objective of the game is to explain as many words as possible in the time allowed. Whichever team guesses the most correct words is the winner.
