I love the ageless, wise folk tales that exist through all cultures around the world. Most cultures have their own versions and there are similarities among them all (but its the differences that count).
We have many already here on the community and will try to list them here for your reference.
Find here many powerpoint stories, in simple language, that you can use in class. Read together or provide to the students for their own reading. Makes lessons based upon them....
Take a look at the story category on Gif Linugua.
Korean Folktales I've created are HERE. As well as audio retelling of those stories.
Find some nice proverbs attached for use as stories in class.
Here are some nice presentations highlighting proverbs related to different animals. Really cool! Can your students guess and state the lesson they teach in good old plain English!?
