For years, I have loved Ed Emberley's drawing books for kids, but I somehow missed out on this fabulous book of his until recently. It's awesome for many reasons-- great focus on parts of the body for EAL learners, (most) kids love anything with monsters, and the cutouts in the book make it extra fun.
There is also an iPad app that we used in class, and the app has made the book into a song. Now that I know the song, I find that I can't read the book anymore. I have to sing as it's folky and cute!
