Optical illusions are a great warmer, cooler or filler for your class. Here's a powerpoint show that I made from pictures I found on Google. It takes five to ten minutes depending on how chatty your students are
I ask students to look at each picture and answer three questions.
1. What is the first picture you notice?
2. What is the second picture you notice?
3. Do you like this picture?
