This particular model, Moses and the Plagues of Egypt, is created in order to portray the 10 plagues that the Egyptians experienced, described in the book of Exodus in chapters 7 through 12.
With this set comes also a photo booklet illustrating the story using the actual model pieces. You can read the story with your children or use this as ideas to retell the story in your own words using the figures and scenery from the model.
