Here’s another great idea for the classroom from Ollena Jackson, Virginia Cooperative Extension:
This year, I ran a contest for the first grade classes in one of my schools. I made them a chart and if every student drank (low-fat) milk for lunch in the cafeteria they got to put a got milk sticker on the chart. The class with the most stickers won and OWG Christmas tree for their classroom. I am loaning a small tree with my plush characters from the small Organ Annie doll as decorations.
