At the beginning of the year I have each student write down at least two things about themselves that others may not know. I then put one thing each has written into a grid and give a copy of the grid to everyone in the class. I ask the students to find the person who wrote each characteristic or experience and have that person sign their box. I'm sure to model how to discover the owners of the ideas by asking a question. 'Are you the person who owns the iguana?' or ' Are you the person who puts ketchup on peanut butter sandwiches?' This avoids the mass signature approach, demonstrates a way to begin a conversation, and provides a good way for the students to get acquainted in an active and positive way.
