August House learning site has a section on their website called Story Cove with free, animated stories you can watch online.
They have an excellent selection. Maybe I am bias but I have always loved Aesop’s Fables and any kind of myths- particularly Native American and African ones.
The site has several sections and you can watch Aesops’ Fables online, Indian folktakes, West African folktales.
You do need flass to watch the stories, they are easy to navigate and use by even younger kids.
