About the store

I started my career as an accountant. I taught economics, science, and mathematics at a small high school for many years. After earning my masters degree in math, I began teaching at the community college level. My children have renewed my interest in K-12 mathematics and I have been rewarded by discovering a blossoming online math community from which I can learn and develop as a college instructor.
