I don't have any consequences except for a massive increase in blood pressure! (Kidding...I know what you meant!) However, the consequences for most kids are "Do it now." or "Do it at recess" depending on what I've got planned. This would be for infrequent lapses. Not just once, but every month or so. For one student, it's "You can't stay after school with me on Tuesday." He loves to stay after. Wacka-doo kid. Parents don't care whether he does it or not. For another, it's "Well, that's a first. I'm sure it won't happen again." And it doesn't. (She's crying while she's telling me.) For a most others, it's "Let me sign your agenda, and fill out this form and get a parent signature." Those are for the kids whose parents will go to town on them. The form was on a Power Teaching site.
