This game played with a hula hoop and bean bags demonstrates all the math that can be explored with a simple tossing game. Start with a small set of beanbags, no more than 5 or 6. Each child gets to toss the beanbags one by one into the hoop. How many land inside the hoop? How many land outside of the hoop? How many beanbags in all? Each round gives children practice seeing and naming smaller parts of a total number in a variety of ways.
