On the first day of kindergarten in September, Ms. Bradley says, “Each day of school I will add a jelly bean to this jar. When there are 100 jelly beans we’ll have a party to celebrate 100 days of kindergarten.” What will Henry and his classmates do until the big day? In October, they share special things at show and tell. In November, they remember what they are thankful for. December brings a day to play in the snow, and in January, Henry discovers a favorite library book. Before they know it, the 100th day arrives! Now how will they celebrate?
