Students work with the Doyle’s story in a fun and engaging way. It has been written out in the form of clues. There are 25 clues to solve this mystery. Students can get them all at once and then they try to solve the case or you can make it more fun and for example hide the clues around the classroom or them away as some kind of reward – I do that when we are reviewing some area we have already covered – when the group answer the question (from the area that is being reviewed) correctly they will get a clue. If they don’t answer correctly, they will not get a clue. The students try to get as many clues as possible to solve the case. So they are not just reviewing a selected topic but they are solving a mystery at the same time.
