Celebrate diversity, math, and the power of storytelling!

Tyson is the youngest-smaller than his four older brothers and always trying to keep up. But when the family's pet gerbil, Swish, goes missing, it's Tyson to the rescue! Tyson uses his knowledge of doubles, triples, and sizes to figure out a clever way to reach his beloved pet. A playful exploration of proportional thinking, featuring an author letter about the ubiquitous nature of math.


Storytelling Math celebrates children using math in their daily adventures as they play, build, and discover the world around them. Joyful stories and hands-on activities make it easy for kids and their grown-ups to explore everyday math together. Developed in collaboration with math experts at STEM education non-profit TERC, under a grant from the Heising-Simons Foundation.
