How have theme with Billy Goats Gruff
The theme Billy Goats Gruff: I have several times used the moving shadow play on the wall for this and other fairy tales, with music to.
(If so fortunate to have an old overhead, can be used for many exciting things.) And Puppet / shadow theater is also widely used. Tells first, then the children investigate, try and play afterwards. (Works great for the bigger kids too)
