⭐ Why Teachers & Students Love It

For Teachers: Say goodbye to boring beginning-of-the-year diagnostic tests! No complicated setup required. This math mystery is ideal for assessing retained math skills, spiral review, consolidation, math centers, early-finishers, 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: I recommend pacing this activity by giving students one clue at a time to keep the class at the same point. If using the clues in a different order, keep the suspect list away from students until all five clues are completed and discovered!
