Enclosed is a PowerPoint presentation with several works of art. It is a class activity and introduction to using the Elements of Art and Principles of Design to break down parts of a work of art and see how it works.
There is a work sample at the start and several images thereafter to work with. The directions ask that students write their answers down with several prompting questions. After that, a good classroom discussion may help everyone understand the concepts more. Feel free to use different images as appropriate, however I found the more abstract the better. Students are then less worried about what the work is or looks like and more concerned with the concepts (Elements of Art and Principles of Design).
