The teacher collects all the secrets and writes them down on one paper. A suggestion is that the students give the secrets to the teacher a day or two before the lesson starts, so the teacher can write down the secrets without stress. The teacher then makes a copy of all the secrets, a copy to each student.

On the lesson the teacher sets up a speed dating scenario, where each pair has one minute to speak before rotating. Students may ask questions, but they are not allowed to ask directly if what’s on the piece of paper is true about them or not. When all the students have talked to each other, they must guess which secret belongs to whom. They write down their guesses on the paper.
