I like this idea for the beginning of the school year, especially for Freshman. " When you close your eyes and think of what you want for college life, what do you see?" encourage people to be honest and open about expectations so you can help the group live up to them.
Homework bingo - If they turn in their homework for that morning they get to write their name on any square. On friday's I will pull out two bingo chips...and whatever names are on that square they will be able to pick out of the treasure box. Know a teacher who does this, the kids love it
