While I was visiting an elementary school library in Chicago last spring, a group of third graders came into the library to return and check out books. The children wore index cards clipped to their shirts. On one side of the card was the child’s name. On the back, layers of sticky labels with the top label indicating the child’s current Lexile reading level. The poor librarian was required to check the reading level on the cards against the books the children wanted to check out. If a child picked a book that wasn’t on their level, she had to take it from them and tell them to get another one. Imagine what it feels like to hear you can’t read a book you want to read and must choose another one. Imagine your entire class witnesses this exchange. How do you feel about reading? How do you see yourself…
