I taught for 15 years; 6 years in 6th grade and 8 years in 5th grade. I spent my last year in 3rd grade and various summers teaching middle school. I also was lead teacher for 5th grade and led many workshops on how to teach 5th grade math. For the past 6 years I have been writing curriculum for many companies including Key Curriculum Press and Kaplan. I also speak at math conferences.
