An Assessment Conundrum: Should we require a specific path to the answer in our quizzes and tests? If a student solves a problem in an unexpected way, should they get full credit?
Teachers’ Mathematics: going deeper into what we teach.
Math as Literacy: this is the ninth in a series of posts in defense of high school math.
Updates to my Math Education Page
I improved the looks of the virtual geoboard to make it more useful for creating images to copy-paste into documents.
Housekeeping: I annotated the Directory of Directories, mostly with grade level information. I added the Abstract Algebra launch page to the list, which now has 41 links. Also: I added three links to the site’s front page, and rearranged it to make the newsletter, rights, and email links more prominent. I tweaked the Rights and Permissions page.
I added a directory of all the representations and activities about rate of change.
All Math Education Page Updates
What else is new
14 January 2023: I presented “Geometric Puzzles: Tiles and Rep-Tiles” at the San Francisco Math Teachers’ Circle. More info on my Talks page.

18 August 2022: I sent out my e-newsletter, with links to recent blog posts and new material on my website. Subscribe!
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.
Note: All material on this site is copyrighted. You may reproduce it for any non-commercial purpose, as long as you credit me and link to the blog. More info.
I do not publish guest posts by people I don’t know, so don’t bother asking.
(I am also involved in word puzzles, especially cryptic crosswords.
More on this.)
