This lesson plan introduces students to the concepts of happiness, sharing, helping, and volunteering. It involves students watching a short film and videos about "Mr. Happy Man", discussing quotes about happiness and love, and reflecting on what they've learned. The goal is for students to improve their speaking, listening, and vocabulary related to these topics and to become more sensitive, thoughtful, and aware of finding happiness through helping others. Activities include describing photos, watching videos, discussing in groups, creating a spidergram on understanding happiness, and reflecting on different perspectives on volunteering.
