The Arithmechicks and Mouse are heading to a spectacular fair! As they enjoy the rides and games, the Arithmechicks discover fractions at every stop along the way. But when one chick doesn't feel included, it fractures the group. 1 sad chick/9 happy chicks ...means less fun for everyone. How will the Arithmechicks become whole again? Luckily, they love math and one another so much they turn a disappointing day into an amazing adventure.
