In this lesson, students use multiplication to understand the problem of single-use plastics and how they impact climate change.

Step 1 - Inquire: Students describe a photo, wonder about the origin of the plastic waste they see, and identify their feelings surrounding plastic pollution.

Step 2 - Investigate: Students complete multi-step math problems about single-use plastic water bottles, and learn about the connection between disposable plastics, pollution, and climate change.

Step 3 - Inspire: Students complete multiplication problems that show how small positive actions can have a big impact, brainstorm about the use of disposable plastics in their school, home, or community, and write a letter to persuade someone to take action to reduce the use of plastic.
