Materials: two rolls of toilet paper (perforated, so it's easy to tear)

1.Have all the students sit at their desk, without talking.
2.Take out two rolls of TP and tell the students to "Take as much as you think you'll need." This provokes a lot of questions, but DO NOT say anything more.
3.Send a roll around at both sides of the room (this helps the activity to move along more quickly).
4.Once all students have taken "what they need," collect the unused TP.
5.Now tell the students that for each square they ripped off, they have to give one fact about themselves.
There are other variations of this game that use candy (M&M's, Smarties, etc.)-- you can improvise and use any material you want
