Here is a teacher generated Tree Map about graphing rational functions. I used it to summarize three days of activities, discussions and examples about the complexities of rational functions. The students were asking lots of questions about particular procedures and parts of the examples, but I didn't think they had a strong grasp of the whole picture. Using the Tree Map was very helpful because it made obvious the differences between local and global behavior. It also helped to categorize all of the procedures and definitions and examples we had discussed.
