LIA & LUÍS

In this entry in the Storytelling Math series, children are introduced to the concepts of measuring and comparing.

Brazilian Portuguese–speaking siblings Lia and Luís have a relationship marked by a little rivalry. Luís is quick to brag, and Lia doesn’t mind, usually. As they play with blocks, Luís’ tower may be taller, but Lia’s tower—patiently built—doesn’t fall over as easily. When they go to their family’s store for snacks—biscoito de polvilho (tapioca biscuits) for Luís, coxinhas de galinha (chicken croquettes) for Lia—the rivalry continues: “I have more!” brags Luis. But does he? The children compare their snacks by container size (height, width, depth), quantity, and finally by weight. It looks like Lia may finally be the winner, but a sad look on her brother’s face gives her an idea. Sharing a bit of her croquette makes the two sides equal. Simple and uncluttered illustrations follow the children as they try different ways of comparing. There is a sprinkling of Brazilian Portuguese scattered throughout the text (a glossary can be found at the end). The children and their father are portrayed with olive skin and black hair. The backmatter includes more on the math concepts and suggestions of strategies adults can use with children to further develop their measuring skills.
