Planning peripheral perception - 4 of 4

Let us suppose the teacher is "drilling" "What's your  name?" "What's your  occupation?" etc. S/he divides the class into two groups for pair work. The members of one group are hotel receptionists; of the other, guests checking in. When the 'receptionists" have asked all the "What's your -----?" questions, and the "guests" have answered all these questions, the teacher, before getting everyone to change roles, will add a new element:  this time, the receptionists are hard of hearing. In the new situation, amid howls of laughter and much shouting, the repetition is camouflaged.
