This idea has been all over the Chorister's FB group and has been getting RAVE reviews so I thought I'd give it a try. It also coordinates so well with my Song Hospital program review found HERE.
Prep is super easy...just buy some colored dot stickers at Wal-Mart or Amazon has them here:
Then I've seen 2 ways to have the activity run:
One is to have the teachers, presidency or yourself hand a sticker to great singers (give them the Musical Measels) in between each song/verse/phrase/etc. The more they have by the end of singing time, the better.
The second is to have the kids put stickers on you (give you the Muscal Measels) if they are caught being good singers by their teacher. I could potentially see this option to be a little less-rowdy as the kids aren't trying to sing while covered in stickers (I know, hard, right!?). And they may get a kick out of you being covered!
