⭐ Why Teachers & Students Love It
For Teachers: Say goodbye to overwhelming prep times before the holiday! No complicated setup required. This math mystery is ideal for 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 this math activity will vary between 30 minutes to 2 hours. I recommend pacing this activity by giving students one clue at a time. Once the whole class has completed a clue, move on to the next. 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!”
