**Ms. Sue**, Sunday, September 1, 2013 at 8:23pmAlthough I was an English and social studies teacher, occasionally I taught a section of 7th grade math. When I discovered that I was only about 95% accurate when demonstrating on the board, I was embarrassed. I told the class that if they discovered I had made a stupid mistake, I'd give anyone extra credit for politely calling it to my attention. Worked like a charm. <g>

**MathMate**, Sunday, September 1, 2013 at 8:36pmI was thinking of something along the same lines, but couldn't find a good way to put it in action. Thank you for sharing the bright idea.

**Steve**, Monday, September 2, 2013 at 4:10amI recall my class in analytic geometry in high school. There was one guy named Andy who would read a comic or something during one of Mr. Jarmon's involved solutions. After two blackboards were filled with equations and things didn't come out right, Andy would look up and in a few seconds point out where the teacher had erred. He'd have been loaded up with extra credit in your class, Ms Sue! Of course, he naturally didn't need it.
