Graphic organizers

I loved our last class. We had so much fun and I do not think I will ever forget those chapter in the book we read. I have done readers theatre with students in the past, but never in that way. I gave the students a few sentences to read and the created a little skit and performed it in front of their peers. I loved how we took the chapter and put it into our own words. This strategy helps you to analyze the text rather than simply remembering it. The way we did it in class took it from a DOK 1 to a DOK 3-4. I think with younger children they will have to be prompted more and a "I do, we do, you do" strategy would have to be incorporated into that type of readers theatre because children lack that creative bug and more wrapped around giving the teacher what they think she/he wants rather than creating their own personal expression. I noticed this in a 5th grade classroom when the teacher told them to create a new cast that would help other 5th graders with compound and complex sentences. She explained the criteria and split them into groups and they just sat there starring at each other like lost puppy dogs.
The Chapter-
Quote: The science of teaching may be knowing what to do; the art of teaching lies in knowing when to do it. This quote in the book stood out to me because I have never really looked at teaching in that light. You always think of teachers as that person that knows their content, but a person can have all the knowledge in the world with bad timing and learning will never take place. Think about it, if the teacher has the knowledge but no idea how or when to present it then no one learns.
Question: Alright author, You have explained graphic organizers in great detail with various strategies. My question is how do I use these pre-reading/pre-activity strategies in an elementary classroom? I am able to implement these graphic organizers after the information has been presented, but how do I do it before we talk about without giving the students all the information they will gain before we read or discuss?
Personal connection: I connected to this chapter because I absolutely LOVE graphic organizers. I use them all the time in my learning process. They help me store information into my "long term folder". I am a visual learner so organizing information into a picture rather than words help me grasp information more effectively. I loved the different strategies used in the text and will be useful to me in my future classroom.
