Can't you pay the students off with "extra credit" for a blanket, er recess party?
I'm sure you could go to the front office for some test papers while leaving the class alone to deal with this...student.
I gotta be honest, there were teachers that used to blister that ass for not putting your hand up and being called upon when I was a kid...holes in the paddle and all. You screwed around and acted like a jackass in class you got sent to the Vice-Principal's office...the Dean of Punishment.
Hell, I occupied a seat outside mine in junior high school. I was like his private screener. Wimpy crying babies got sent in. Hardened criminals got to go out back of the gym and smoke with me. I LIVED in that guy's hallway! He always had 3 things to offer up...
1) Paddling...over and done with.
2) Detention...You were going to miss your bus.
3) Bring in your parents.
#3 was a toughie. If you skipped #1 and went to #3...you might get #1 x2 at home!
You had to measure your options.
PS...when confronted with smoking in the bathroom...it's best to finish the smoke. They already busted you. You might as well finish it!
