It was one of those crazy Fridays. A couple teachers weren't covered, so I walked into this 4th period 7th grade math class cold. And the lesson plans were a little sparse.
The kiddos finished the worksheet in 15 minutes.
Well, I do have a math game...
It's a pretty simple time killer. I put them into teams (in the past I've let the teams pick their own names), and then each team gets a chance to guess the number I've thought of. It's a three-digit number with no repeating digits (a number such as 982, 670, 251, etc). I let them know if they got any correct digits as well as if any are in the correct spot in the number.
Once they get the idea, they really get into it.
So, I had to come up with a number. And since I had just arrived to the classroom, the classroom number was on my mind. But they'd figure that out in a heartbeat, right?
It took them more than a dozen guesses. They got close a couple times. One team guessed 409. When I gave them that 2 of the digits were correct and those 2 digits were in the correct spots, I was sure someone would get it. But first they guessed 405 (they were sure 5 was in the number), 406, and 402. And in the midst of this, one team gave me 509. (They wouldn't let go of that 5.)
Finally, at about guess 16, one team gave me the number.
And I pointed out that the number was the room number.
Of course, most of the time the kiddos have no idea what room number they're in. Seriously.
(A student asks for a pass to go back to a previous class to retrieve something they've forgotten. I ask what room. They hem and haw. I ask which teacher. That they usually know. And I'll write the teacher's name on the pass. Or I'll know the room number from the teacher's name. This happens so frequently that it's barely worth remarking about.)
