This is a great site to send students to when they ask, "I don't know what to read!" Have them type in a title or author that they do enjoy into What Should I Read Next? and the site will produce a list of similar books that they may enjoy. Have them click on the book next to the title for an Amazon summary of the book. A search of Frindle resulted in 50 different suggestions! Although the book suggestions are not by Reader's Workshop bands, they are similar and often in the same band as the original book. To see the readability, have them go to Scholastic's Book Wizard.
Great site for a Library or to have bookmarked on a computer in your classroom!
