These Reading Level Lexile Posters have been designed with library organization in mind. You get a regular Lexile poster, a Scholastic Reading Counts Lexile levels poster, and an Accelerated Reader (AR) levels poster. These are the colors that I use to color-code my library. The labels I use are available on TPT. You can also purchase from DEMCO the colored overlay spine labels to organize your books. The colors make it easier for students to choose the book appropriate for their reading level.
