I think a lot about my math teaching. Perhaps too much. This is my outlet. I hope you find it interesting and that you’ll let me know how it’s going.

Thanks for reading.

my background

I got started as a middle school teacher in the Saint Paul Public Schools. I taught seventh and eighth grade for six years.

I left the public school classroom to work on my Ph.D. at Michigan State University, where I was a graduate assistant on the revision of the Connected Mathematics materials (we were writing CMP2).

I now teach in the math department at Normandale Community College in Bloomington, MN, where I am working very hard on course development in (1) content courses for future elementary teachers, and (2) College Algebra.

I have worked with teachers around the country on Connected Math implementations. I worked part time with the Connected Math authors on another revision—CMP3—this one motivated by the Common Core State Standards.

I am interested in hard questions about teaching, and I am interested in children’s mathematical development. You should find evidence of both in the writing I do here.

  1. Thank you for doing this, excellent idea. It will be my new morning destination for stimulating ideas and future topics of discussion. My condolences to Perez Hilton for I no longer need your verbal swag!

  3. I started teaching CMP I 8 years ago – I’m sold on it… too bad most people are not… overthinking math pedagogy is what wakes me up at night.

    It is fascinating to read what you have written…

  4. Our family lasted three winters in St. Cloud — came there straight from Vietnam, the culture shock was no match for the drastic temperature change. Wonderful blog, Christopher, thank you.

  5. I just found your blog and it looks so interesting! You might also be interested in participating on the Mathematics Teaching Community at https://mathematicsteachingcommunity.math.uga.edu
    For example, you can post links back to this blog there.

  6. Greetings! I am a sixth grade Math teacher and I found your blog through your discussion on place value and the Mayan number system. I am trying to start of next year with a look at number systems. The students start Social Studies looking at the Sumerians and I thought I could:
    1) Make a connection to that
    2) Help students deeply understand what place value is and means.

    Any ideas on how to teach this? I am trying to come up with an easy and simple way for students to work with another number system…

    • Michael, easy and simple do not pertain to the study of alternate number systems.

      Nonetheless, I do take requests!

      A bunch of ideas and resources come to mind. I’ll throw your question into the hopper for near-term posts.
