My colleague, Tifani Daly, conducted a character census of independent reading books in her 6th grade classes. Take a look.
WOW! Kids were really surprised to see white, straight guys as the most represented characters with straight, white girls a close second. I guess I was surprised too. Students expressed an interest in reading about more diverse characters. Looks like I need to do more to build and promote a collection that meets this need.
