This activity can be used as individual or group/partner practice of Order of Operations. It is similar to a scoot activity, with a twist! After each problem is finished, the students will get a clue to solve the mystery. After each answer, the students will mark off a suspect, location or tool to help solve the mystery. There are 10 questions that help solve the Mystery. If you enjoy this Mystery math activity, try a few of my other C.S.I activities below: Easter math C.S.I ActivityEaster math
