TEACHING EXPERIENCE

I have taught math for 17 years in the classroom. Subects include: basic math, hands-on algebra, geoometry, trigonometry, AP computer programming, and learning support (college). I left the classroom in 2005 to work with CEISMC (Center of Education Intergrating Science Math and Computing) at Georgia Tech. While at CEISMC I conducted teacher professional development conferences for teachers - grade 3 to grade 12.

MY TEACHING STYLE

Project- based learning -- hands-on. My goal is to have students finish my classes liking math and knowing that they are capable in mathematics.
