Enter the world of giraffes, math, and science in this informative picture book that introduces important STEM concepts through the animal kingdom’s most beloved gentle giants, for fans of Ten Magic Butterflies and Zero the Hero.
Twiga the giraffe introduces young readers to fascinating facts about giraffes and their relationship to other creatures—all by using math concepts such as measurements, graphs, shapes, word problems, and more.  

Readers will learn: 
– That a giraffe’s hooves are as large as a medium-sized pizza
– That their heart can pump up to 16 gallons of blood through their body every minute 
– And that giraffes can run up to 31 miles per hour – and they weigh over 4,000 pounds!  
This interactive picture book explores important STEM concepts through fun details about these spectacular animals—from the top of their ossicones to the bottom of their hooves. Back matter includes a glossary of terms, a map of giraffe geography, and a giraffe quiz to test kids’ knowledge.

  • Praise for Giraffe Math:
    A CBC-NSTA Best STEM Book
    A CBC Librarian Favorite

    "An interesting combination of information about giraffes and mathematical connections to this majestic animal. Twiga the giraffe guides readers through different giraffe facts starting with height and weight using U.S. measuring standards (feet, inches, pounds) and making connections between the tallest land animal and an average third grader along with other animals…. Giraffes are truly amazing creatures and the math connections in this work are interesting and well presented."
