Ok - I confess. I love to level books! I spend lots of time and way too much money searching for, buying and leveling books for the leveled library in my classroom. I send books (my own books) home with each student to practice at night. My students take the books home in special book bags, get a parent signature and return them the next day (hopefully).
One of the tools I use to help find the levels of books is the Scholastic Teacher Book Wizard. If you don't already use it, check it out!
I made this instruction sheet for the Book Wizard site for my staff and our parents to use. We use the Fountas/Pinnell leveling system, so we use the guided reading level from the site. I adjusted the form so you can just check off the leveling system that you use. Hope it's helpful!
