Circulo! Esfera! / Circle! Sphere!

Now in Spanish bilingual editions--Caldecott Honor winner Grace Lin celebrates math for every kid in this board book series.

Manny and his friends Olivia and Mei blow bubbles in this playful introduction to geometry. Manny's wand is a circle. Olivia's wand is a square. Mei's wand is a heart. What shape will their bubbles be? (Surprise! They're all spheres.)

The Storytelling Math series shows that all children can be mathematical thinkers. Each book includes ideas for exploring math at home with your children, developed in collaboration with math experts at STEM education nonprofit TERC Inc., under a grant from the Heising-Simons Foundation.
