Experience

I am in my 24th year of teaching mathematics. I usually teach Geometry, Algebra II, Precalculus, and Calculus. Sometimes I teach a class of Algebra I or Intermediate Algebra. I also teach a financial class to help students with basic financial real world questions.

Teaching style

I mostly use a teacher directed style of teaching, however, I love to have the students "discover". This year, I am doing a lot of activities with the students and hope to find some that you have created or create ones that I can share! Powerpoints can be downloaded into smart suite to use with the students virtually. Hello Smart is an awesome way to teach students.
