These look quite fun, and will be great for rewarding the students! I will probably do stickers instead of hole punching because it is quicker – it could also be altered as a whole class chart. My coteacher and I were discussing starting something like that during nap time to try and keep children on their mats for sleeping. Since we only have 3 Super Friend hats, I would need to think of another reward for filling a certain amount of the individual cards, but the whole class chart would be getting up a bit early (if children were not asleep) to do a quiet table activity. I can really see these doing wonders, and I might start them tomorrow or the sticker charts that I created previously for some of the students.
