Here’s a sample rubric for good sportsmanship. I do use that term, even with kindergartners, because I figure they might as well start off learning terminology that we’ll continue to use in the future. When teaching kids how to join in a game, we do a lot of videotaped rehearsals and practice with puppets and peers. Most of my kiddos hate to lose (me, too!) so I give them opportunities to win games and then gradually wean them off victory into the “real” world. They enjoy hearing how I used to cheat my sister at Monopoly (“Oh, my teacher is human!”) and I emphasize candor as we navigate the winning and losing issues. Obviously, some rubrics for good sportsmanship will have a greater focus on simply joining in, because some kids are at a loss during recess. Other kids need more emphasis on playing fair or managing their feelings if they lose a game. The best rubrics are individualized and supported by direct instruction.
