For all those Early Childhood and Elementary Teachers, I have the perfect idea for a literacy unit for you! Meet the Common Core push for comparing and contrasting stories with similar characters and happenings and a respect for diversity all in one unit! Do a "Cinderella Around the World Unit!" There are countless versions of Cinderella. Off the top of my head I can think of: American, Mexican, Chinese, Korean, Irish, Spice Islands, Australian, etc.
Each day or every other day read a new version and then give each child a stamp on their passport!
