A series of famous pictures to promote higher level thinking skills: what might be happening/have happened? What might happen next? Great for EAL too - describe the pictures. Ask them to start by answering the wh- questions and then make inferences. If you play the youtube clip included first, it will show your students that they can say what they think and that there are no right or wrong answers. Well, there are thousands of great paintings and each one can provide a great starter for your lesson. The questions fly in - just incase they need a prompt!
