I created a game in which the students use the locations in Rome as the "rooms," the famous people of Rome as the possible suspects and the achievements as the possible stolen item. In order to discover who committed the crime, where and for what achievement, students need to ask the teacher questions to eliminate possible suspects, locations and clues. For example, is the person who committed the crime a famous Roman leader who was assassinated (Julius Caesar). If the teacher says "no" then students can eliminate Julius Caesar as the possible suspect.
I have included directions for students, direction for teacher setup, a picture of the board game I created and hints for students to use when Making a Suggestion.
