Celebrate diversity, math, and the power of storytelling!

Twins Lia and Luís argue over who has more of their favorite Brazilian snacks. The siblings compare amounts using measurement, counting, estimation, and finally weight to pick the winner. The solution involves clever math--and a little sharing.

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.
