This book is a charming children's book that follows siblings Lia and Luis as they learn about comparing quantities through a playful counting game. The book features relatable situations and colorful illustrations that engage young readers while introducing them to important math concepts like comparison and estimation. In the classroom, this book can serve as a fun and educational tool for teaching students about quantity comparison and the concept of "more" and "less." Teachers can use the book as a springboard for hands-on activities such as comparing objects, counting items, or using number lines to visualize quantities. The sibling relationship in the story also offers an opportunity to discuss cooperation and respectful communication. ( )

The Brazilian twins: Lia and Luis, are given snacks by their parents and compare how much each other got. They compared the size, number, and weight of their snacks to see who had more. It was shown how they got different answers for different units they used when counting the numbers. Blocks were used when comparing the size. Overall, different techniques are used to show the different ways you can compare objects. I enjoyed this book for its inclusion of diversity but also because it can be related to real-world objects. For example, students at lunch can compare the snacks they have similar to Luis and Lia and compare the similarities and differences. ( )
