Join the Arithmechicks and Mouse as they head off to the fair! These chicks can't wait to enjoy the roller coaster, bumper cars, games, and delicious snacks; meanwhile Mouse is determined to sink the rooster at the dunk tank. As the Arithmechicks explore the fair, they find ways to show how fractions work in the world. But when one chick doesn't get to select an activity, the day doesn't go according to plan until the chicks decide they all need to play fair. This book includes a helpful glossary with further information about fractions, while the story provides an exuberant introduction to essential math for young children and their caregivers.
