Enough With the Seashells

Sid brings home an estimation jar from school, filled to the top with seashells. He’s determined to guess how many there are, but he has a problem…there are too many shells to count! At school, Sid and his friends learn a new strategy for making their best guess -- estimation! Now Sid can estimate just about anything -- shells, toys, leaves and stars in the sky!
