I'm enjoying this line of thought....because we are all there! I sometimes
"flag" a class that has a history of clean-up issues. All the ideas so far
have been great and I use a lot them (counting, pick up a certain # of
things, not getting to line up etc..) But if it seems nothing is working
and one class is always late getting out... I tell them "I'm sorry but
next time you will have to stop 5 minutes earlier and start cleaning up.
Usually it takes 5 minutes but since you can't get it done in 5 we will
have to take 10 and you will get less time to work on great
projects,etc...." I put their classes name on a sign somewhere or mark it
on my seating chart so I will remember. Usually they will work hard to get
back their 5 minutes. But sometimes there is just that class that needs
more time. Marking it down helps me to remember which one out of 24 needs
more clean up time.
