This playful picture book demonstrates key math concepts to children in a merry story featuring the Arithmechicks, ten math-loving chicks.

The Arithmechicks have invited their new friend Mouse for a sleepover. When Mama says it’s time for bed, the clever chicks decide it’s time to prolong the fun instead! During the story, readers are invited to count and take away during everyone’s favorite game of hide-and-seek–and to find Mouse, who hides in a different place in each illustration — until all settle down for bed in the warm, cozy conclusion. The book is the perfect introduction to essential math for young children and their caregivers. It includes a helpful glossary that defines the eight arithmetic strategies the chicks use throughout the story.
