One of my students favourite projects, the murder mystery project is excellent for 2nd year students finishing up preterite vs imperfect usage or for 3rd year students as a review of the concept. Students create their own powerpoint murder mystery where they present the victim, 3 suspects and the crime scene. Using preterite and imperfect they include motives, locations, descriptions, personality characteristics in a creative and unique presentation. I assign this project in pairs but a student could easily complete it alone. Students present their mysteries to classmates in powerpoint and peers can make their guess to arrest before the last slide gets revealed. This project won an award as a Missouri Best Lesson Showcase project. Project instructions are in English, model examples in Spanish, project could be easily adapted to Passe Compose/Imparfait usage in French.
