From the So You Want To Be A... Series - 2026 Purple Dragonfly Book Awards, Grand Prize Winner
Right now, somewhere in New York City, two people have exactly the same number of hairs on their heads. Nobody has counted. With one simple idea, a mathematician can prove it.
Mathematics is far bigger than times tables and worksheets. It is the hunt for hidden patterns, the thrill of solving puzzles that stumped people for centuries, and the joy of proving something true forever. So You Want To Be A Mathematician invites curious kids into that world with fascinating true stories, laugh-out-loud moments, and hands-on math activities they can try at the kitchen table.
Young readers will discover why sunflower seeds grow in Fibonacci spirals, why cicadas count in prime numbers, and why a pattern that works four times in a row can suddenly break. They'll learn how one mathematician carved a formula into a Dublin bridge, and how another paid off a math prize with a live goose on national television. Along the way they'll meet famous mathematicians whose stories inspire, including Emmy Noether, Srinivasa Ramanujan, Katherine Johnson, Maryam Mirzakhani, Zu Chongzhi and June Huh. Several of them were once told they weren't good at math.
This career-exploration book also gives an honest, age-appropriate look at the real job. Readers learn what mathematicians actually do, the difference between pure and applied math, where mathematicians work and how much they earn. They see the path through school and college, and the best and hardest parts of a life spent solving problems. They find out how math keeps medicines safe, guides Coast Guard rescues, protects online payments, powers GPS and even brought the snow in Frozen to life.
Kids don't just read about math. They do it. They can make a Möbius strip, test the unsolved Collatz conjecture, discover the magic number 6174, prove Homer Simpson wrong and play Sprouts, a game invented by famous mathematicians. The book closes with a kid-friendly glossary, a heartfelt author's note and a resource guide to the best math books, websites, competitions and museums for young learners.
Written for ages 10 to 14 and accessible to readers 8 and up, this illustrated STEM book is perfect for:
Curious kids who love puzzles, logic, codes, patterns and asking "why?"
Reluctant math students who need to see that being stuck is part of the adventure
Parents, teachers and homeschool families looking for engaging math enrichment, STEM career education and a great read-aloud
Gift-givers searching for a meaningful book for a budding scientist, engineer, coder or mathematician
Part of the acclaimed So You Want To Be A... series of career books for kids, which treats young readers as intellectual equals and shows the real wonder of every profession.
