This flow chart is easy to customize and gets to the point. For my lower level students, I would complete the worksheet with them in class or I would have them work in pairs. It would typically take all class period with my students. For higher level students I would take the answer choices away and give them the opportunity to expand on their ideas. For those students it took about 20 minutes. Regardless, all of my students got something out of this assignment.
Please excuse the thumbnail. It squished my flow chart together and made it look like a hot mess. Please be assured that is not what the document looks like, but it gives you an idea.
