The Association for Library Service to Children updated the Graphic Novels Reading List. It is a wonderful resource that highlights the best graphic novels for grades K through 8. I hope you will share it with your colleagues and students. Maybe you'll even mention it on your library or classroom website. I shared the lists with parents during parent-teacher conferences.
It is broken down into grade levels:
K - 2nd grade - Color
K - 2nd grade - Black and White
3rd - 5th grade - Color
3rd - 5th grade - Black and White
6th - 8th grade - Black and White
