It's basically pictures, drawings, of people with several kinds of aches and pains, such as headache, sore throat, bleeding. It can be used in many ways: oral evaluation, class presentation, written practice. It's a bit raw, indeed. So you guys can add lines, or questions, such as "What's the matter?", or "What's wrong with ... ?". Students can answer in the form of "He should see a doctor" or "She should take an aspirin." I think it can be very useful. I've already tried it out, and it worked! Have a nice class!
