Draw the following pictures, and post them at the front of the room out of order.
Ask the children to put these in the order of the song while you sing the song. Sing and tap a child on the shoulder to move the picture to the right place. (I put magnets on the back so they will stick to a whiteboard or chalkboard.)
Keep singing and tapping children until all the pictures are put in the order of the song.
Now ask the children to sing only the words on the drawings while you sing everything else. Sing the song, the children singing the words on the drawings and you singing everything else.
Switch and the children sing only the words that are NOT on the drawings while you sing the words ON the drawings.
Bear a short and simple testimony of being called of God.
The children love the challenge of this activity and they love figuring out the puzzle of what comes next.
