A murder mystery game. Can be played as a read run like activity or have all the clues in an envelope and have the group read them. Definitely many different ways you could implement this!
My students like the read/run style activity - so we generally have everyone in pairs. The JTE and I will hang the clues up around the classroom and have the students take turns being the reader/writer. I'll dramatically read the story and then pass out the worksheet - go over who the suspects are and what the weapons are. Once we know they understand - off they go!
*editing to mention that I highly recommend adding some BGM and turning the lights on and off while reading the situation.
