By creating their own symbol of God's power and presence in their lives, the children will learn to regularly recall God's presence and depend on God whenever they are in need.
Another option would be to start with larger rocks, about the size of a softball. These could be decorated in a similar way, and the children could keep them in their rooms at home when they are finished. A larger rock could provide enough room for a short Scripture quote, such as, ?God is my rock of refuge . . .? (Psalm 18:3)
If there are children in your group with special needs (physical, visual, hearing, language, or behavioral disabilities), adapt the activity accordingly.
