In this first-grade health lesson plan, the engaging introduction prompts students to reflect on their growth from age four. Using the book "When I Was Little" by Jamie Lee Curtis, the lesson explores the changes in what children can do as they grow older. The interactive element of testing activities and the hands-on worksheet activity, where students cut and glue pictures, effectively reinforces the learning objectives. The lesson embraces the idea that children develop at their own pace, promoting individual growth. However, there is an opportunity to further connect the lesson with the role of health in mental and physical growth. Additionally, considering diverse learning styles and potential accommodations could enhance inclusivity. Overall, the lesson effectively engages students in understanding their developmental changes and encourages a positive perspective on individual growth.
