This simple sign-in sheet is what I use to ensure that my students are reading books that are leveled according to their lexile. It is specifically titled to support the Scholastic reading program "Reading Counts." Students will write their assigned lexile range at the top and then will be required to only read books that fall within that range. You can have peers check the range, or check it yourself. There's also a column to check off when they have tested on the book. This is the only way I can make sure that students are reading books that are appropriate each and every time. After all, if the book is too easy or too hard, they are not growing as a reader. Investing time using something like this will pay you back 10 fold because they are growing as a reader each and every time they read in your class - guaranteed!
