🕵️ The Mystery Case: The Case of the Litterbug 🌎

• Clue 3 Math Worksheets: Calculate the mean, median, and mode.

⭐ Why Teachers & Students Love It

For Teachers: Say goodbye to overwhelming prep times! No complicated setup required. This math mystery is ideal for Earth Day celebrations, spiral review, consolidation, math centers, early-finishers, homework, or the sub-tub.

For Students: It feels like a game, but there is significant math practice and consolidation involved. Middle schoolers are fully motivated by the process of elimination and the thrill of solving a real mystery!

Teacher Tip: Time to complete will vary anywhere between 30 minutes to 2 hours depending on how familiar your students are with the format and the math skills. I recommend pacing this activity by giving students one clue at a time. New math content presented? Make a lesson out of it by modeling the math before diving into the clue. I like to say, “we must learn something new before attempting the next clue!”
