I ran across Photofunia yesterday and thought that it was a cool tool. Here is a quick activity using the app that won’t take much time to set up, but will be fun to do with your class.
Take a picture of yourself, or maybe even a student and create a picture using the app. Do this before class, so when you reveal the picture they will be surprised.
For the assignment, I would have the students get out a piece of paper and a writing utensil and tell them that I want them to write for 5 minutes on the prompt that I am going project on the board.
Wait until they are ready, and then show the picture. Let them look at it and work on their own without any help. I think that most students will take a minute to think about what is really going on. I am sure that many will question how the picture was made. Don’t tell them anything. Tell them to write and see what they come up with.
