I looked at the bulletin board and somehow laughed internally at the situation the three of us were experiencing, and I hoped that the teacher would return soon. Meanwhile, the boys started whispering something, and they laughed, but I didn't hear what. After a few minutes, I returned to them and stood by them, checking the outcome of the task of at least one student.
