Each morning I have a new yes/no question posted on my pocket chart. The kiddos know as part of their morning routine that they need to answer the question by moving their picture to the correct column. The left over pictures tell me who is absent. During calendar time we analyze the data and decide which number "greater gator" chomps. My kiddos are so good at it, they actually write a new question each afternoon and get the pocket chart all ready for the morning.
