This was one of the days that make it worth while. In my "best" classes, ie the ones before lunch and better behaved, there were discussions of math happening all day. Beyond that in my 2nd period, arguments with each other over exponent rules. I have the same students for 2nd and 3rd periods, for Algebra and Math Support. They finished with their quizzes way faster than I anticipated, blew through the worksheet that was supposed to last for 3rd period (6th/7th didn't even finish said worksheet for perspective) so I suggested 10 minutes of a "game" and 15 minutes to do their homework when they were done with everything I'd prepped 3 0 minutes early. So, we start the "Find the Treasure" game. Basically I pick a spot to "bury treasure" on an x-y plane and they "hunt" for it by calling out points. I tell them how many "steps" they are from it. Thus they implement logic calculations and have to remember that (1,5) means right 1, up 5. Well, the three teams got so into trying to out guess each other thaat we played the full 30 minutes and they didn't even want time to do their homework.
