In this clever picture book, six different shapes attend Shapeston Elementary School along with the children: Triangle, Square, Circle, Rectangle, Rhombus (or "Diamond" to her friends) and Oval. As the story begins, the big news at school is the upcoming play. Everyone is looking forward to auditioning, especially the shapes. One by one they are introduced, with descriptions of their unique personalities and interests, along with the roles they've played before (Triangle as a tortilla chip, Oval as a skating rink, Diamond as a kite and the like). Happily, after all the wonderful auditions, the drama teacher decides everyone gets to be in the play.
