This year I began the year telling the kids about the Fantastic Four.  I explained about how each member of the team had special strengths and weakness and when they all worked together, these strengths and weaknesses balanced each other out.  Then, I gave them the following handout.  I asked the students to think about what their imaginary strength or super power might be and also what their real "super power" is.  At the end of each class, I've been picking two kids that have been acting fantastic and also asking the class to pick two more kids that they saw being fantastic.  It all adds up to a Fantastic Four for each class.
