I saw this idea a while back actually, used it in my class and thought it was fantastic!
Students obtain clues (obviously in English in this case) by answering a series of questions related to the material which has been taught in class, whether it be grammar or vocabulary. The clues essentially help the students to escape from the classroom, upon which point, they receive a group prize.
It’s extremely competitive and great fun. I used QR codes with this game too, which meant my students had to move around the class and find information using technology.
Has anyone else had experience with these type of activities?
