With a PhD in math from Princeton I chose to teach at an elementary school and write a math-inspired children's book. AMA!
My short bio: I am Sasha Fradkin, a mathematician with a PhD from Princeton University. Last year, I became the Head of Math at a small elementary school. I develop the math curriculum and teach children in grades K-5. I have coauthored a math-inspired fantasy book for children, and we are running a kickstarter for it now. Ask me anything!
