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.

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.
