Thoughts: I love to have children be the voice and share their stories about faith in their own lives. With all my heart I believe that we need to teach our children how to reflect on their own lives and to share the principles that they have learned.
A few days a ahead of time I call the children in primary. I like to split into groups and have the kids telling the stories rotate and the kids on the groups stay where they are. I like to have no more than 5-7 kids per group.
I have each child to plan for a 1-2 min sharing (repeated for x number of groups). I give the families a lot of flexibility. I just told them that their child will need to share a story about how they chose the right, or a story where they had to make a choice and how they decided and what happened as a result. They may bring a visual aide, write it down and read it off the paper or what ever they feel comfortable doing.
I find that children sharing with children make the stories more real and developmentally appropriate since all the children are much more likely to experience something similar.
