We started class with a group activity involving one other teacher and one student, and then I wanted to sit down with Bobby and do some science. We talked a bit about black holes, but Bobby was so very eager to play chess. I could tell it was going to be a tad difficult to get him to engage in science at that stage, so I thought chess might be an excellent focusing activity. It sure was! Bobby is an excellent chess player, one can really see his analytical skills come to the fore. Bobby remained very concentrated for more than twenty minutes in a row.
