I saw this website mentioned recently: www.purposegames.com. This is only a matching activity- picture to words, but it would be great for a quick warm-up activity. You can also have students race against each other. It seems that you can set up a tournament between classes. I really liked this particular game on the present progressive. You can see how it works before setting up your own. They have many games for Spanish and French. While it would be good to customize these games for your own students, there are a lot of basics here like colors and South American countries. No need to reinvent the wheel! Has anyone used it? How did your students like it?
