As a note, these are ideas once you've learned the basic song. You'll need some sort of visual to teach the words to the children... these are in addition to that visual.* Power to Choose Stick- Make a little wooden stick the primary's power to choose stick. While singing the song a primary friend can hold the stick up front as long as they like, within reason, and then they can point it to another primary friend- they have the power to choose! That friend then comes to the front and you keep on pointing, choosing and singing. Remember, the person up front has to sing too!
* Children of God, finger puppets!! (HERE is a link for simple ones you can print off on heavy paper) You'll actually need puppets they can use their fingers as legs. The smaller movement helps them concentrate especially hard! Tell the primary children you have a bunch of little friends, children of God, that need help learning a new song! While you sing the song, children put the puppets on their fingers and listen closely for directions. For the first verse the puppets can step touch side to side while you sing. For the 2nd verse the puppets can kick. Ask the children if they can think of any movements for their puppets to do! The song is in a 3/4 time signature, which is what is used for waltzes, so the puppets could even waltz in a triangle.
* The chorus of the song talks about "special light". Bring in some "special lights"! Close the lights and turn on your "special lights" while you sing. Some "special lights" could include a Christmas star, lava lamp, flashlight, glow in the dark stars, light saber, fun night light, a chain of Christmas lights. Are those pretty cool? Wrap it up by singing the last time with the ultimate and most "special light"- a picture of Jesus Christ.
* Mystery Children of God- Get some video of friends in the ward singing this song. Each Sunday the children will hear a different person on the video singing and try to guess who that Child of God is. For example, you could get the missionaries, the bishop, the young women... etc. I have a digital camera and would just record on that, let the primary children hear and then after the guess, play it again and let them see who was singing and sing along too! They are hearing the song and learning the melody as they listen over and over.
Another simpler version of the one above is to have a child come to the front and turn with their backs facing the children. You tap 5-6 children on the shoulder who stand up and sing the song. Then they sit down. The person up front turns around and tries to guess what Child of God was singing!
* All over the world, children of God can choose the right! HERE is a wonderful link from The Friend with different CTR shields in different languages. There are 15 so you could invite 5 children up at a time per verse of this song and have them hold up the shield while you sing. After the verse you can have them guess what language it is. You could reuse these easily for the song Choose the Right.
