Stephanie Forsman—who wrote many of the math lessons on our Math at Home website—has been teaching in the New York City independent school system for more than 15 years. She is currently a fourth-grade teacher at The Berkeley Carroll School in Brooklyn, where she previously taught at the second- and third-grade levels. She has served as a facilitator for Mathematics in the City, a research and professional development center with a mission to “transform classrooms into communities of mathematicians, where children explore interesting problems and, like mathematicians, engage in crafting solutions, justifications and proofs.” She has presented workshops on Math Puzzles & Logic Games, Technology and Math and Napier’s Bones at national conferences and served as the math subcommittee chair for the accreditation group conducting the New York State Association of Independent Schools’ 10-year school accreditation reviews in 2013. Stephanie earned her B.A. in art history and fine art at Trinity College in Washington, DC, and her M.Ed. in elementary education and museum education at Bank Street College in New York City. She also served as a Peace Corps volunteer in Mali, West Africa.
