My youngest is a brilliant, albeit extremely lazy person, who does math in his head and has from a young age. He doesn't like to "do the work" involved in working out a problem and so just puts down the answers.
Well, as you can imagine, teachers hate this and insist on him showing his work. We've had conferences to this effect and, being a little like my son myself, I questioned why this has to be done. She replied so that, if he gets any wrong, they can see where he made a mistake and review the problem...which is fair, IMO, but my son doesn't work out a problem like most of us would, as his mind works in unconventional ways.
She also complained to me about an incident where she marked one of his answers wrong and he had the audacity to correct her. The answer was correct and hers was wrong, but she still would not capitulate because he didn't show his work. She didn't feel that a 6 th grader should argue a point with a teacher. He didn't actually argue, just brought it to her attention.
I had to explain to her that I've always taught him to stand up for what is right and, unfortunately, he was right in this case. She was NOT pleased!
During their time together he found many more of her mistakes and quietly pointed them out to her, in the cases where she had marked his papers wrong. I never heard anymore complaints about the subject!
