Rebecca Rapoport holds degrees in mathematics from Harvard University and Michigan State. From her first job out of college, as one of the pioneers of Harvard's Internet education offerings, she has been passionate about encouraging her love for math in others. As an early contributor to both retail giant Amazon.com and Akamai Technologies, the number one firm in cloud computing, Rapoport played a key role in several elements of the Internet revolution. She then returned to her first love, education, as an innovator of new methods to introduce children and adults to the critically important world of STEAM education as COO of an enrichment center dedicated to helping kids explore the creative side of science, technology, engineering, art, and math, and is currently developing and teaching innovative math curricula in the Boston area. Rapoport is also the co-author of Math Games Lab for Kids (published by Quarry Books), a book of fun, hands-on math activities designed to introduce elementary and middle-school students to several areas of higher math; and the calendars Mathematics: Your Daily Epsilon of Math 2021,Mathematics: Your Daily Epsilon of Math 2020, Mathematics 2019: Your Daily Epsilon of Math, and The Mathematics Calendar 2018, all published by Rock Point. She has an Erdös number of 2.
J.A. Yoder is an educator and engineer who has a lifetime love of puzzles and patterns. Her educational philosophy is that hands-on creative work is both the most fun and the most effective way to learn. She developed and taught the original hands-on-math lessons for an after-school program that eventually inspired this book. Some of her happiest memories come from "eureka moments"--either from learning something that makes a dozen other things suddenly make sense, or the sense of accomplishment that comes from solving a clever puzzle. The only thing better is sharing this joy with others.
