Students will work in small groups to cooperatively to complete a Fermi math problem. Fermi math challenges students to solve seemingly complicated questions using estimation, rounding, approximations, analytical thinking, creative thinking, communication, and technology skills. The students will investigate the driving question: If you wanted to send a valentine card to each person in the world next year:
• how many boxes of packaged valentines will you need to purchase?
• how much will it cost for you to purchase and mail all of the cards?
• if everyone in the world sent a valentine to everyone else in the world, how many valentines in total would be sent?

Students increase their media literacy skills by critically examining and revising junk mail.

In this activity, students are provided with a list of supplies that survived their plane's crash in the Amazon jungle. They will organize the supplies to classify which items are useful for surviving in the Amazon. Students will use estimation and basic math skills to determine how much they can carry and to decide on what items to bring with them to survive in the Amazon until they reach their destination.
