My students keep referring back to this ever since we did it a little while ago and probably what led to much success on the test covering this chapter. (I saw kids draw it out on the back of their test!). As they are getting ready for finals this week, I am sure many of them are looking back at this so I figured you might want to see it too. It is nothing fancy but I see similar ones in textbooks. When students get to create it on their own, they actually remember it better!
