Does your school have a book room or leveled book library for guided reading? Recently, I worked at Lovett Elementary in HISD (Houston) where they have a wonderful book room with guided reading books for teachers to check out. We held planning meetings in this room on my visit. So handy for being able to quickly refer to texts as we learned together about improving small group instruction.
Several years ago I worked with Spring Branch ISD in Houston and visited every elementary to help set up a leveled book library tailored to the needs of that school. It was such an interesting project! There were so many ways in which to organize the space and the books.
Here are a few photos of leveled book libraries used by entire schools.
