I love this idea! Here is a video explanation (she calls it a Melody Map but it's really a Word Map...).
The point is to have the Primary "crack the code" -- Each dot is one word in the song. This one I've done for THE FAMILY IS OF GOD I made the GREEN dots forms of "me" or "us," BLUE dots forms of "God/Father" (as in Heavenly Father), PURPLE dots word relating to family -- ie "family, children, mother, father," and BLACK dots for all other words.
You can sing the song over and over and over this way. If they haven't gotten it after a few times you can help them by pointing to each dot as you sing. Once they've figured it out you can split them in half and one half sings the color dots and the other half sings the black dots, and then switch! You can have them stand when it's their word(s) for good and extra movement, and extra fun!
