TEACHING EXPERIENCE

I taught Algebra/Geometry in High school for 4 years. I also have been teaching pre-AP Algebra and 8th grade Math in middle school for the last 6 years.

MY TEACHING STYLE

Technology heavy teaching style. I made my own virtual whiteboard with a Wii remote and I use powerpoint presentations and things like the eInstruction remotes all the time.

HONORS/AWARDS/SHINING TEACHER MOMENT

My students think I'm awesome, does that count? hehe And the old saying about always a bridesmaid and never a bride applies to me and the teacher of the year voting at my school. They like me enough to keep putting me on the ballot, but I never seem to win. Personally, I think it's because I'm in a portable building and they think less of me because of that. :)

MY OWN EDUCATIONAL HISTORY

BS in Math from the University of Texas

ADDITIONAL BIOGRAPHICAL INFORMATION

I am a native Houstonian who is back home teaching math to at-risk kids. This is definitely NOT what I saw myself doing when I was a student, but I love every minute of it. I am also a father to an awesome, rambunctious 3 year old boy.
