You click on the start button to make the four pictures appear. One is a dog. The students either call out the answer (if you're doing it quickly) or if they are in groups one member rushes to you with the answer. Then click on the arrow to see the pictures again. If you click on answer check it will circle the dog. Otherwise click on arrow again to go to the next screen.
