word chains
This works well with French High School pupils:
You divide the class into teams (no more than 5 in a team) and give each team a chalk or pen and access to a black or whiteboard (or a large piece of paper). You give each team a word to start with and then start the timer. The pupils have 1 minute to write a list of words in a chain. The last letter of the first word is the first letter of the second word and so on. After one minute, the team with the most words (without repeating words) wins. I play it several times up to say, 5 wins. If there are repetitions or spelling mistakes the count stops at the last correct or non-repeated word. This encourages pupils to take care even though they are having to think and write quickly.
