The opportunities for recognition, and fun, are endless. The levels have nothing to do with one's age, merely one's responses. This concept teaches students to move easily to whatever level is appropriate. Problem students often love the attention they get from disrupting the class. Students rarely pick seatmates based on productivity.
Social considerations are far more important.
Students must understand that you use a seating chart to make sure that both teams are productive and competitive, that students who are strong or weak, in terms of behavior, are equally spread between the two teams so that the former can be leaders, and the latter are relatively isolated from each other. Telling students upfront that this is your procedure and rationale helps students to accept the procedure. Or you could let the team with more points have free seating.
