This site has interesting prompts with great graphics that will inspire your students to be creative. Great for a center or whole-class activity, each post is thought-provoking and sure to spark interest. I almost got side-tracked, myself, as I was getting information for this post. I have not viewed all of the over 200 prompts, but please remember, especially if you are an elementary teacher, to preview the topics and pics before you choose to link to them or use them in class.
