No Best Way: I give two examples (one in geometry, one in algebra) where I believe it is a mistake to choose “the best way” to teach something. Better involve your students in a conversation about the two options!

A guest post by Liz Caffrey: Lab Gear, the Great Connector. She spells out how she uses these manipulatives in 7th and 8th grade.

A letter to teachers in their first year: Dear Young Teacher. I tried to step back from the terrible conditions of the past couple of years, and write about the bigger picture of getting started in this line of work. I followed up with some thoughts about Mentoring Young Teachers.

Updates to my Math Education Page

I added a video presentation of A New Path to the Quadratic Formula. This is an approach that does not involve parabolas or completing the square. (It is based on Constant Sums, Constant Products.)

I added Slumber Theory, an exploration involving prime numbers and divisibility tests. I included The Vampire Riddle, a TED-Ed animation I scripted on this topic. I embedded A Riddle of Fire and Ice —a TED-Ed animation I scripted— in my Map Coloring page.

I added the outline of a unit on Completing the Square.

Other News

27 November 2018: I moved my blog into WordPress (here.) I thought the move had happened smoothly, but some graphics, and some entire posts, failed to materialize. Also, many links are broken. If you come across these problems, please notify me, indicating which post had the issue. Thanks!

I have retired from the classroom after 42 years as a math teacher in K-12 — from counting to calculus. I now work with teachers and schools:
    Math Education Consulting

I share instructional materials on my Math Education Page, and my views about math education on this blog

On this page: announcements about new material, updates, etc. on the site; new publications; my appearances at conferences; and my other activities in math education.
