Instructional Ideas

• Create an interdisciplinary project between math, environmental science, and language arts
• Have class members research a current environmental concern and graph the behavior over time in the same way

Classroom Considerations

• Resource is designed for elementary learners, but math concepts may be more appropriate for middle schoolers
• Most effective after a class reading of The Lorax

Pros

• Provides links to additional lesson plans to reinforce the concept
• Comes with lesson extensions and discussion topics on the story's themes

Cons

• None
