c is math, and songs can solve noisy problems in the third book in the Great Mathemachicken series, written by New York Times bestselling author Nancy Krulik and illustrated by Charlie Alder.

Chirpy the chicken is not feeling very chipper when a group of birds calling themselves the Crow Family Band keeps the coop awake with their loud singing. She's supposed to be the Great Mathemachicken, but math can't solve their sleep problems. Or can it?

At school, Chirpy and Quackers are singing a new tune as they take a trip to the music classroom. There, they learn about musical notes, which seem to work an awful lot like fractions.

And when she sees how Mrs. Zoober's students, singing high and low, together make one wonderful tune, she gets a egg-stra good idea how the chickens might join forces . . . and even add some feathered new friends to the mix, to make something truly special.

The third book in the Great Mathemachicken chapter book series, combines New York Times bestselling author Nancy Krulik's trademark humor and clever wordplay with hilarious and lively two-color artwork from the incredibly talented Charlie Alder, to create an engrossing and charming STEAM-based adventure that will have young readers clucking for more.
