Mini Mathematical Murder Mysteries: Sixteen Activities to Stretch and Engage Ages 11-13, Paperback

The students are given the data or a diagram to solve a "problem" - which of four characters is a murderer. To find out, the student must solve all or most of the questions on the sheet to identify wrong answers as well as correct ones. Problems are staged, so there is an element of suspense for the individual...and racing between students to solve the mystery.
