Technology in Math Education: Some probably controversial thoughts about going all in on tech in the math classroom.

We Need to Review! I share some thoughts on how to make review most effective.

A guest post by Liz Caffrey: Lab Gear, the Great Connector. She spells out how she uses these manipulatives in 7th and 8th grade pre-algebra and algebra. And a guest post by Meghan Lee: Polyarcs in the Classroom, on how she uses these manipulatives in her high school geometry class.

Updates to my Math Education Page

I added a Precalculus directory.

I tweaked and updated Geometry of the Conic Sections — including four different GeoGebra constructions.

I added 12 videos about the Lab Gear for teachers, a free at-home professional development program. I added a Lab Gear Q and A page, and reorganized the Lab Gear home page. I expanded and updated the Algebra Manipulatives: Comparison and History page.

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.
