No, I am not a teacher. But, I love books and think the Scholastic website is an excellent source for children's book related information. My opinion has just recently skyrocketed due to their new FREE Teacher Book Wizard Widget. I've been fawning over it for the past few days and think it is an incredible resource for teachers as well as for parents interested in helping their children learn to read.
If you've ever wanted to know the reading level for a book (interest and grade levels) or needed to find a guide for a certain book, this widget is for you! Teacher Book Wizard Widget searches over 50,000 children’s books from all publishers. To search for a book using the widget you just type in a title, author or keyword. The widget will provide a list pertinent to your search with author and illustrator information, and a listing of reading level for the books. Book Detail pages display reading levels in all four systems. Sometimes the result also includes series information as well as links to available guides, activities and lesson plans. This same area of the Scholastic Teachers Website includes a BookALike Search engine and a shared Book List feature.
For example, if you search for "Corduroy" a list of all Corduroy books appears. Looking at the Detailed view for Corduroy by Don Freeman, it gives the following information and links to free teaching resources:
Interest Level: K - 2
Grade Level Equivalent: 3.2
Lexile Framework: 600L
Guided Reading: K
Topics:Friends and Friendship, Games and Toys
Go ahead and try it out. I've found it quite useful myself!
