Taking Notes vs. Doing Math: In which I take on a sacred cow — teach math, not note-taking!

Learning from Teaching: A couple of interesting tidbits discovered by participants in my Visual Algebra workshop.

Geometry: A Guided Inquiry: Another book review, this time about the book that had the biggest impact on my teaching and curriculum development, by far.

Updates to my Math Education Page

Function Diagram for y=1/x: I added a cool-looking static diagram. (If you’re baffled, here’s the function diagrams home page.)

Applets Directory: I added links to my off-site arithmetic games (signed numbers, and complex numbers). Programmed in Snap! by Parisa Safa.

Summer Workshops: This is the page about my 2019 summer workshop: Visual Algebra (grades 6-9), in two locations: June in Silicon Valley, August near Boston. I added a link to the participants’ website. I also added mentions of continuing education / graduate school units, the 75% scholarship for public school teachers, and the free and discounted manipulatives from Didax and Nasco.

What else is new

5 July 2019: I fixed more broken links, this time in a series of posts in which I challenge the dogmatic stance of teachers who are overly stingy about offering hints to students who are stuck: About Hints, About Hints, the sequel, and Hints! The topic that will not die.

15 March 2019: I sent my e-newsletter out. The main topics were story tables, an argument against the shrinking of geometry, a book review, geoboards + related topics, and the announcement of my summer workshops. Subscribe!

9 January 2019: I will offer a grades 6-9 version of my workshop on Visual Algebra twice this summer: June 25-27 at Synapse School in Silicon Valley, and again August 7-9 at Atrium School near Boston. More information.

Old 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:

I share instructional materials on my Math Education Page, and my views on 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.
