Updates to my Math Education Page
I added Leonardo’s Areas (involving the area of circles) and Squaring Pentominoes, a dissection puzzle set.
I added “Geometric Puzzles for Prospective Math Teachers“, a chapter I contributed to a forthcoming book for professors who teach geometry to preservice teachers. The chapter includes links to Tiling, Geometric Puzzles, and Geoboard materials on my website.
I added links to relevant blog posts on my Middle School home page.

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.
