It was the last week of summer school, a play, some absences, and a bit of this and that had my math class down to two students. I sat down between them and decided to teach them how to factor trinomials. They were getting it and were working independently when one let out a large moan.
"Why did you moan?"
"I didn't moan"
"When was the last time you lied to me?"
Then the jazz switch went off in my brain and I was talking jazz, and Art Blakey and jazz messengers, and Bennie Golson setting up an all Philly band and within 30 seconds, the room was jamming and factoring.
