TEACHING EXPERIENCE

This is a shared account for my wife, who teaches biology and chemistry, and me, who teaches geometry. She has taught 9th-12th grade sciences. I've taught only 10th grade math. My wife has taught all the core sciences the last 4 plus years depending on what the school needed. I've taught geometry my 4 plus years.

MY TEACHING STYLE

Visit www.doucehouse.com to view my geometry website. My wife is very creative in her teaching style. She likes to create lots of fun things for the kids to do to learn the subject matter. I like to create a lot of my own material because I often times think the material that is at hand is either not at the quality level I want or because it isn't challenging enough for my students. I've also spent a lot of time putting together a geometry website for my students to use that includes videos of math lessons I teach throughout the year, and I have some interactive lessons on it. Visit www.doucehouse.com to view my geometry website.
