Tip: A good goal for games is that the game in itself is fun enough to play even if you are not trying to practice a language.
Guess the person 
Have each student write the names of about eight famous people on slips of paper, fold up the slips and collect them in one pile. Form teams of at least two people. One person takes a slip of paper and tries to get his team to guess the name written there without saying the name or its spelling. Each team should have about one minute per round. For every name that the team guesses correctly, it receives one point (they can keep the slip of paper to count). At the end of the time, the team that guessed the most names correctly, wins.
