The Stories
Lia & Luís: Who Has More?
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. Available in hardcover and paperback.

Let's Learn Portuguese!
As you listen to this recording, keep in mind that Brazil is a very large country. Like in the US, people in different parts of the country have different accents. Also, Brazil is not the only country in the world to have Portuguese as its official language. People in Portugal, Angola, Mozambique, and other countries also speak Portuguese. And they too speak with different accents.
Have fun trying all these new words!
