We all like to think we can solve a murder given the right clues. Here's another chance to use mathematics skills to identify "whodunnit" - following the great success of the first book in the series Mini Mathematical Murder Mysteries. The students are given the data or a diagram to solve a "problem" - which is always 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. 12-14 years
