Synopsis by the author/publisher
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.
“Luis has 1, 2, 3, ... 98, 99, 100 biscuits. A hundred is way more than two. Luis wins. No doubt. Lia is still not convinced. After all, one biscuit is much smaller and lighter than a croquette.”
Official review by MathsThroughStories.org:
Ana Crespo’s ‘Lia & Luis Who Has More?’ (2020) is a part of Charlesbridge’s Storytelling Math series which promotes diversity (e.g., gender and ethnicity) in mathematical stories. The story follows two competitive siblings, Lia and Luis, who are given two different snacks by their father: a bag of only two large heavy croquettes for Lia and a bag of 100 small and light biscuits for Luis. Using different ways of measurement comparison, they want to prove to each other that they have more snacks than the other sibling by examining whose bag is taller, who has a larger quantity of snacks, and whose snack weighs more. How can they tell who has more? The story is very engaging and there are so many follow-up activities that teachers and parents can do with their children once they have read the story, for example, children could be given two bags of different toys of different sizes, and asked for ideas to see which bag they would like to have and why. Through various mathematical investigations to see which bag is taller, heavier or has more toys in it, they will be asked to give their mathematical reasoning. Like the other titles in the series, there are also a few activity ideas given at the back of the book. The page illustrations by Giovana Medeiros are so visually appealing and help young readers to clearly visualise the mathematical concepts behind the story. We like that the story is told and illustrated by an author and an illustrator who share the same cultural heritage as the characters in the story. All in all, we highly recommend ‘Lia & Luis Who Has More?’ ​to either introduce (or reinforce) the concept of measurement comparison to children, aged 5+ years old. (Disclaimer: We received a complimentary inspection copy of this book from the publisher/author.)

Recommended age range: 
5+ years old
