To use mobiles to help the children understand the Trinity
The children will identify the Trinity as the Father, Son, and Holy Spirit.
Prepare the rectangles ahead of time by punching holes in them as follows: the large rectangle should have three holes punched at equally spaced intervals across the top and bottom of the 12" width of the rectangle; the small rectangles should have one hole punched at the top center of the 3" width of the rectangle.
Encourage the children to use large, simple symbols in each small rectangle instead of a lot of different objects. One symbol in each small rectangle will be easier to associate with the particular person of the Trinity.
If there are children in your group with special needs (physical, visual, hearing, language, or behavioral disabilities), adapt the activity accordingly.
