My students absolutely LOVE playing Crime Solvers cases in my classroom. The first few we did as a whole class and now we use them in our math centers. They are self-checking and really motivate students to practice their math skills.
Here's how this activity works. Students read the case file which gives them all the details on the mystery and their objective. They read through all 6 suspect cards and report on whether each suspect is innocent or guilty using their case report worksheet. They'll know a suspect is guilty if their math doesn't add up. They have to work through all the suspect cards because most times, there is more than one culprit! After solving the case, students read the 'Case Closed' brief and learn the culprits' motives and consequences.
'The Case of the Sour Lemons' focuses on evaluating expressions. The skills they will review with this activity include vocabulary, computation, error analysis, and word problems. Students can work independently or with peers to solve the case.
