The Case
There's a friendly first-week mystery to crack, and the clues come from getting to know the class. Students work through a line-up of suspects, answering back-to-school questions and using their answers to rule suspects out one at a time — an easy, low-pressure way to build community before the real work begins.
How the Mystery Works
Your students become detectives. They answer each getting-to-know-you clue, then use their responses to eliminate suspects from the line-up until only the culprit remains — a collaborative, high-engagement way to start the year.
