Please add your lessons and suggestions for teaching preschoolers The Parable of the Prodigal Son to this topic.
I was in charge of the childcare for volunteers' children during River Community Church's Marketplace Vacation Bible School, 2011-2015. We were working our way through the Old Testament, starting with Creation in 2011, but also tied in some New Testament stories. They were not detailed lesson plans, but I am sharing all of my teaching notes here, in case the general ideas from my rough outlines are of use to someone.
We filled our 3 1/2 hours each day with story and activities related to some of the same stories the "big" (elementary aged) children were studying. Most of the time was spent in learning centers related to the day’s story and in free play, so it was not truly rotation, but many ideas were gleaned from this site and some ideas listed here could be expanded to full Sunday-school-hour-long lessons for younger children.
Each year we had a different overarching theme for the week. Those are included in the lesson notes below. Some of the activities tie into those as well.
