The lesson teaches kindergarten students about character emotions in the story "The Rainbow Fish" by having them read the story with a puppet. As they read, students are asked how the characters feel based on their facial expressions and words. They then come up to interact with a smart board game to match character emotions to different stages of the story. The goal is for students to understand character feelings and relate their own experiences to how the characters change from selfish to sharing over the course of the tale.
