Elements Learning

Hi all, I'm a current Photoshop user (ACE certified) but will be starting up a teaching class on Photoshop Elements at a local prison for a few inmates who are part of a visual arts program. They have very basic computer experience. Can anyone suggest learning tools/books for these guys. I cannot use internet or download learning materials in the prison and must only be in printed format. I need an easy to follow book on learning Elements for them. I have just downloaded the program so that I can learn the difference between full PS and Elements. Thanks so much.
