In this lesson, students use multiplication skills to understand the problem of single-use plastics, learn how disposable plastics impact climate change, and write letters to encourage others to reduce the use of plastic in their family, school, or community.

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.

Learning Outcomes

Students will be able to:

• Use four operations to solve word problems.
• Solve multi-step word problems with a letter standing for the unknown quantity.
• Understand the impact of disposable plastic on climate change.
• Identify ways to reduce the use of disposable plastic.
• Write an opinion supported by reasons and facts.
