What else is new

17 December 2018: I restored the Geoboard Problems for Teachers post.

15 December 2018: I restored my Polyarcs post, which had not survived the move to WordPress. Interesting discussion in the comments!

14 December 2018: I found the graphics from my Stumped by Euclidea blog post on the Internet Archive’s Wayback Machine! It was a bit of work to put them back into the post, but not as much work as recreating them! I’ll continue to work my way back through the posts to restore content lost in the move from Blogger.

1 December 2018: I attended the California Math Council Northern Section meeting in Asilomar. My presentation was about Reaching the Full Range of students in a heterogeneous class (i.e. any class). I put lots of links about this on my Talks page. See above for links to blog posts about sessions I attended.

Old News

Henri Picciotto

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, and I continue to develop curriculum.

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.
