Race the clock and your partner in a Word Search competition. Pairs each get a different word search, but it has the same hidden terms. When you call time, whoever has the most unique words wins a point per word (if we both found "sport" neither wins a point but if only one person found "game" then they score a point.
Once that's over, create sentences with the words you found. Add in the faire du and the jouer au. Win 2 points for each perfect sentence! Because word finds are totally useless unless you DO something with the words. ;-)
