Fairy Tales do not stop with Cinderella, although many teachers do. On this site find in-depth annotation/analysis of 49 fairy tales, modern interpretations (including some media), illustrations. Links to at least 40 full-text eBooks expands student reading into a global library of folklore and tales. This the meat and potatoes of cross-cultural reading, of core classics, of CCSS-type analysis. Not just for kids - many of these stories lexile at the HS level.
Go on - enrich students with some of the UR plotlines, characters, settings, and conflicts. Let them run with it. I would also use Roderick Pullman's new "retellings" of the same tales, by the way. And throw in a few episodes of Grimm and Once Upon a Time. On their own, students can access Shrek and a host of other movies, from animations to dark and stark. Speaking of dark, HS students (and MS selectively) should read some of the poems in "Transformations" (Anne Sexton).
