Some other (older) pages on the blog:

• GeoGebra. I still develop applets but mostly for mathart, as lessons have moved more to Desmos Activities.
• Interactives. Collection of digital activities.
• Twitter.  A start up guide for preservice teachers especially. Outdated, but even then surpassed by Exploring the Math-Twitter-Blog-o-Sphere. Now most of the discussion has moved to Bluesky, though there are Twitter diehards.
• Quotations. On math, teaching, and learning. I love a good quotation. See also, these quotes from my tumblr with graphics.
• Reading and Viewing Recommedations. Curated starting places for our preservice teachers and people new to the #MTBoS.
