Now that I have had this bulletin board up for over a year, my students get "The big idea." My students are young so it isn't always easy but they are focusing on the author's message now more than random events in the story. My themes lesson is on my teacher sites. I hope some of you will find it helpful.
These posters also look great when you print two to a page and then you have more room in your classroom for more wonderful posters. Look for this here.
