This is a simple and very helpful flow chart to identify the AUTHOR'S PURPOSE of a text. I suggest printing a class set, then laminating them. Placing them in page protectors also works very well, if you don't have access to a laminating machine.
I allow my students to use this graphic organizer on assignments and quizzes, and I would even sign out the aid for homework. Also, I make it available on my class website, so students always have access to it.
