This is one of my favorite Prezis! I made this as a positive perspective message. The main theme was that you see the world as YOU are. I love optical illusions. I have used some of these with my kindergarten class, but I think the main idea is definitely for older students. Anyone can enjoy the individual optical illusions. This is a Prezi of 53 slides that you can click through with the arrow and spend as much time on each slide as you want. I went through all the optical illusions I could find and picked the ones I thought were the best. I had fun making this. I hope you enjoy it! One is a video that is really neat. This would be great for any grade to talk about perspective or the way you look at things, art classes, or any grade just for fun to see some optical illusions!
