I am a 1st year 5th grade teacher. Does anyone else use StoryTown Harcourt reading program? If so, how do you organize your small group (guided reading) leveled reader books? So far I have each colored book in a matching colored folder with the lesson marked on it along with the small group instruction guide. I am finding that they are taking up too much room (i am using hanging folders in a crate). Anyone have any better ideas to store them?
