Teaching math is difficult. Teaching math in an interesting, engaging, and effective manner is even more difficult. This blog is dedicated to brainstorming interesting and dynamic math problems and projects. While this blog isn’t specifically dedicated to Project/Problem Based Learning (PBL) models of instruction, the facilitator of the blog is employed by the New Technology Network of Schools as a Math Coach and hopes to be of service to NT Math teachers. Still, good instruction and interesting teaching isn’t confined to PBL and all are welcome at the table.

Feel free to make yourself at home. You can check out presentations I’ve given or selected blog posts.

About the blog facilitator

I used to teach math at a high school. Then I taught math at a high school using Project Based Learning (PBL). Then I went back to school to get my Master’s degree in Atmospheric Science in Colorado at Colorado State University. But I missed education. So now I’m a Math Coach for the New Tech Network of Schools. Oh, and I’m currently writing a book for Stenhouse Publishers.

  1. Hi, Geoff – I have a question from our engineering design teacher. I sent your Retrospectus out to all our faculty and in reading it, she found Nguyen used as an adjective in several places. Can you tell me what it is in reference to? Thanks for your help!

  2. Oh, and you’re not currently a teacher, either, Geoff. Yet I would not rule you out as having useful things to say about technology in classrooms.
