Godly Play is a form of Christian Education for children of all ages. Godly Play is used occasionally during ASP and Sunday School. Based on Montessori methods of children’s’ learning, it allows children to experience bible stories in ways they can understand, guides them in wondering about their place in the stories, shows them how to create meaning out of the Christian language and liturgical actions, all within an environment designed for them to experience the love and blessing of God. Godly Play may be used during ASP, Sunday School, or Worship.
Here’s a video that gives a good overview of Godly Play.
