Language Arts class requests books

We have a lot of students that prefer to read graphic novels. In our English Language Arts class we encourage students to read if they have some downtime.  We would love any school appropriate (no violent or sexual content) graphic novels to add to our reading shelf.  Diary of a Wimpy Kid is also very popular.   Our shelf has most of the series.  To complete the series we need books ;  3, 6, 7, 8, 9, 15.Another genre would be Fun Facts books, or Weird but True books.
