I think for a lot of children, visuals are the best way to explain concepts. I believe that’s definitely true of the plan of salvation. How many times have you seen someone draw one of those charts on a chalkboard? A lot.
When you want to tell your child (or your class or the whole Primary) about Jesus Christ and some of the miraculous things He did, what better way than to use some of the stories contained in these 3 kits? Kit #1 has His baptism by John and the Temptation. Kit #2 contains the stories of Jesus calling His apostles. Kit #3 tells about the marriage at Cana and the woman at the well.
At my house, where I live with my daughter and her family, I prepare the figures by laminating them and putting hook velcro on the backs, and after telling my little grandsons the stories, I let them play with the figures and tell the stories back to me using my Storyboard. They learn and remember best through play, and they enjoy retelling the stories.
