I was just called as the Chorister in Primary. I was a little overwhelmed by the timing as our primary program is coming up quickly. I really needed to be able to gauge where the kids were at with each of the songs for the program. I saw a "Celestial Singing" idea here and I thought it was the perfect way to help me keep track of the kid's progress, and a great way for them to have a visual of their progress as well.
What I did:
I created my own version of the "Celestial Singing" poster with the star (representing pretty good job), moon (representing very good job), and sun (representing excellent singing or Celestial Singing). For each of the songs in the program, I also created a star with the name of each song. At the beginning of singing time, I'd have a reverent child come up and pick a song for us to run through.
To engage the kids, I bought a couple star shakers from the dollar store. I had a couple children who were being "celestial singers" come up and do the shakers while we sang the next song. I also had a child that was being a "shining" example of a celestial singer come up and help me conduct using a glow stick. I called up new children for each of the songs. They all really seemed to enjoy getting to participate so much.
After we'd sing each song, we determined where we needed to place it on our chart. Over the weeks, the stars have started moving up the chart and we are well on our way to become "Celestial Singers".
