One thing that I loved was the amount of beautiful art work related to St. George and the Dragon. If you do an image search on St. George and the dragon, there are TONS of different amazing works of art that you can learn about.
I love the Book of Virtue Movies.
Listen to Storynory’s audio story of St. George and the Dragon. If you haven’t visited their site yet, you definitely should. They have tons of free audio stories for kids. We visit this website a lot.
