Reviews of Titles for 4th Graders
"The GradeReading.NET suite of sites provides recommendations for contemporary books appropriate for each grade level – it's an online, constantly updated grade level reading list"
It's important for students to be able to find books that are both at an appropriate reading level and interest level. (While I am opposed to leveling books per se, we don't want to swamp a beginning reader either.) This list may give you some good suggestions for the following materials: Contemporary Fiction, Fantasy, Graphic Novels, History, Humor, Mystery, Science Fiction, Sports and more.
The site also offers reading lists for other grades too!
