Here's a background PPT for Storytime 3 telling a simplified (and safe) version of the Little Red Riding Hood story (which the kids will know as 빨간 모자 [pbalgan moja], or 'red hood [hat]').
I left out the moral of 'don't talk to strangers or take shortcuts' and the 'what big (eyes, ears, teeth) you have' bits for simplicity/time, and the book version doesn't touch on either, anyway. Also, I changed the 'woodsman' in the story to a 'hunter', as I thought it would be easier to explain.
Hope this is helpful as an introduction or to help get the kids interested in the story.
