I have done a camp where I played card and board games with students for a couple of days and then had the students make their own game - card, board or other, and then teach the rules and play the game.
Alternatively, you could look at a Dungeons and Dragons style game (search it on the site its there)
You could give the student several lyric sets and have them choose one song, have them get creative with the lyrics... write them in different places around the school and take video/photo of them and then take a laptop in and have them work with you to put the videos/photos to the sound track and have it shown at the school festival later in the school year
Ask the students what they would like to do... conversation activities, reading stuff, review of textbook so far....
