We realized today that Carson did not complete one page of the test he was given yesterday. So he spent the first portion of the class completing it. When he finished we went through it together. Carson got an 85%. The first two problems he made a silly mistake mixing up a positive and negative number. The other points he lost because he ended up getting 0=-1 which was a correct result, however he wrote "infinite solutions", when it should have been "no solution". We discussed his errors and Carson seemed to understand his mistake. We had 10 minutes left in class so we decided to go play ping pong. Although I contended with him, he still beat me every game! He's really good!
