I read Amazing Grace to a kindergarten group. In it Grace uses her imagination to play different roles, which kindergarteners always love to do. Grace is told by her classmates that she can’t be Peter Pan in the school play because she is a girl, and she is black. Her grandmother takes her to see a ballet of Romeo and Juliet with a black girl playing the Juliet role. Grace practices being Peter Pan and earns the part, and plays it beautifully.
Activity: As an activity, the children were randomly partnered and they were to listen to their partner tell about a talent they had or something they were good at. Each partner then drew the other doing that activity, and told the class about their partner. At the end, we played a "guess the animal" imagination game.
The message was that ALL people have talents and strengths that have nothing to do with skin color (or gender) and that we should appreciate what our classmates have to offer, and build admiration into our ways of thinking about each other. Exclusion always leaves some out (hence racism) but inclusion allows everyone to opt in!
