Each activity can have one or more teachers. In FET, you must specfiy for each activity the exact teachers, so it is not possible directly to assign randomly the teachers.

An indirect approach: consider each students group+room a time slot. So you will have 6 slots (say 2 days, 3 hours per day, or 1 day and 6 hours per day). Add for each teacher an activity without students set. FET will allocate randomly the activities into slots. I don't know how to tell FET that at a single slot (slot 1...6), there have to be allocated only 2 (or 1 or 3) teachers. Maybe you can use this idea and solve what you need, but I am not sure it is possible.
