By Dr. Suess
After re-reading this book, I immediately notice all of the discussions about society and our planet that could be started after reading this book. Especially with the older kids, talking about materialism (thneeds- everyone HAD to have them in the book, yet they were not very useful), pollution, respecting the environment and seeing firsthand in the book what can happen to our beautiful earth if we don't take care of it. All of these topics are so relavent and modern, the teacher could ask kids to bring in articles about global warming, pollution or materialism in our society and relate examples or characters from the book to our world today.
Another great way to use this book, is to analyze Dr. Suess' writing techniques. Of course, the rhyme scheme is always popular with almost any Dr. Suess book. For the younger kids, clapping when they hear a rhyme as you read could be interesting, and with the older kids actually reading and picking out the rhyming words and trying to imitate this style could be more interesting for them. Another interesting literary aspect to explore, is the perspective from which the story is told. It is not just a narrative or a dialogue; there is a beginning story of the young boy paying the old Oncler to tell him the story of the Lorax. This beginning story is quite detailed, and ties into the ending when the Oncler gives the young boy a truffula tree seed to go plant. As a teacher, you could encourage students to try a new style of writing similar to this; create a beginning story that changes how the actual story they are writing is presented. Even if the students don't necessarily like this exact idea, it will hopefully get them thinking outside the box.
