I had an idea in the middle of the week to use marshmallows to motivate the kids (actually my idea was for jaw breakers, so thanks to Mary for talking sense into me). The idea is that for every song the kids sing well I will put a marshmallow in a bowl. At the end of singing time I would put them all in my mouth and try to sing to the kids. There are 12 songs in the program, they got 11 marshmallows in the bowl.
Singing "Popcorn Popping" was kind of ridiculous. I could barely breathe. The kids though sang their hearts out to see me do this. I probably won't ever do it again, but I got great feedback from the kids - they loved it. Figures.
