Scholastic Book Wizard
Scholastic Book Wizard is a great tool for determining the reading level of a book. Simply type in the title or author of the story and Scholastic will search the database to see if they have that book & the level. Be sure to select "Guided Reading" to determine the letter level. This is a great tool; however, it only has the reading level for books printed by Scholastic. Therefore, you may not always find the book on this site.
