Dartmouth Alum Kara Colley is Keeping Math Joyful with New Children's Book

I am proud to be featured on the Dartmouth Physics website. Dartmouth alum Kara (Relyea) Colley '98 has made a successful career out of math education and curriculum writing. Her latest endeavor, My Hundred Friends, is a children's book designed to teach about factors, multiples, and primes using approachable and joyful cartoon characters. In collaboration with illustrator Coley Nielsen and Natural Math Publishing, Kara is currently crowdfunding for their book. You can support the publication of My Hundred Friends by pre-ordering a copy through June 27th. https://physics.dartmouth.edu/news/2026/06/dartmouth-alum-kara-colley-keeping-math-joyful-new-childrens-book
