Common Core Math 101 is a companion site to the book ‘A Parents Survival Guide to Common Core Math’ by Christen Nine M.Ed. [aka Mrs 9 the Math Teacher].

Christen Nine has a Bachelors of Science in Mathematics and a Masters of Education in Moderate Disabilities. She is a certified Secondary Mathematics Teacher through the state of Massachusetts. She has taught high school math, both in the classroom and online, and currently serves on the board of directors for Christian Educators Academy, a private online school.
