Synergy: Celebrating Mathematics

MATHEMATICS is the science of numbers and their use. From counting, arranging, and measuring objects to describing shapes, math is connected with everything we do. Branches of mathematics include arithmetic, algebra, geometry, and calculus.

To understand a concept, it’s useful to read a cluster of books related to a theme. Explore these recently published books for young people:

STORYTELLING MATH is a book series from Charlesbridge featuring children of color applying math to the world around them. Readers are encouraged to become mathematical thinkers. Let’s explore several new books in the series.

Whether searching for eggs or building a bird house, each story celebrates math in the daily lives of children.

LIA & LUIS books are written by Ana Crespo and Giovana Medeiros. In PUZZLED!, the twins who use geometry and sorting skills to decipher a puzzle sent by their grandmother.
