The library teacher provides three lessons as examples of their work: 1. A kindergarten lesson introducing fiction and non-fiction genres using a PowerPoint and game. Students learned to identify the genres and what makes a story fictional or non-fictional. 2. A lesson for grades 1-2 about Earth Day where students listened to a story, learned what Earth Day is for, and made their own books listing ways to help the Earth. 3. A third lesson is mentioned but no details are provided. The teacher aims to improve lessons by adding more critical thinking and hands-on activities.
