Depending on the week's topic, some LDS primary sharing time ideas include using a clock to teach that service can happen at any time, sharing a video to demonstrate the power of repentance, and bringing a suitcase packed with items that can help a person share the gospel. Teach the value of following the prophets by matching quotes from President Monson's talk with key words tied around a chest. After opening all the keys, the chest reveals a surprise.
To teach a sharing time lesson based on the principle of service, draw a clock on the chalkboard, and divide the children into groups. Each group is assigned to a certain time group like noon to 3 p.m., and 3 p.m. to 6 p.m. Give the children time to discuss how they can serve their families during that time, and then bring their ideas back to the rest of the class. This project demonstrates that service can happen at any time.
Teach children about sharing the gospel by bringing a suitcase filled with helpful and unhelpful objects for missionary work. For instance, pack Sunday shoes, a "Preach the Gospel" book, the scriptures and a tithing slip, along with movies and video games. Explain how some ideas help missionary work, while others hinder it.
