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

The Arithmechicks are headed to the beach! Their good friend Mouse is going to compete in a sandcastle contest. The chicks are excited to play all sorts of beach games–including volleyball and surfing–as they cheer on Mouse. Readers are invited to add and subtract as these math-loving chicks also explore fact families–and to watch as Mouse, along with their new friend Crab, create a magnificent sandcastle! Will they win a prize?

This book includes a helpful glossary that defines fact families, providing a playful introduction to essential math for young children and their caregivers.
