Today, I share a guest post by Margot Schou, who I had the good fortune of mentoring at the start of her career. With her permission, I inserted footnotes with links to some relevant further reading on my blog, website, and in the book I co-authored with Professor Robin Pemantle (There is No One Way… Continue reading Mentoring and Coaching

Manipulatives
Liz Caffrey is a master middle school math teacher in the Boston area. She is the author of last year’s Lab Gear, the Great Connector, a guest post on this blog. Today, she shares her big-picture thoughts about manipulatives. I inserted some links to pages on my website — you can find many more links… Continue reading Manipulatives
Teachers’ Mathematics
I recently came across an interesting and humorous lesson, intended to generate discussion and reflection about the properties of our number system. It is based on the idea of a fictional cashier who knows absolutely nothing about numbers. The worksheets (Tarzan 1 | Tarzan 2) were created by mathematician Robin Pemantle for use in a… Continue reading Teachers’ Mathematics
PCMI
In 2006, I attended the Park City Mathematics Institute. I shared some of the work I did there on my website. Here is some information about this summer’s program, from the amazing Peg Cagle. -- Henri —————————————————————————————————— An immersive, three-week residential program, the Park City Mathematics Institute / Teacher Leadership Program provides participating secondary math… Continue reading PCMI
Transformational Geometry for Teachers
I taught geometry for decades, starting in the 1980’s, and loved it. I’m reasonably good at manipulating algebraic symbols, but I don’t especially enjoy it. In contrast, I am happy to spend plenty of time on visual puzzles, and I am enthusiastic about sharing that passion with colleagues and with students. Early in my high… Continue reading Transformational Geometry for Teachers
Asilomar Report: Conic Sections
As my retirement starts to kick in, I no longer attend conferences — except for one: the annual meeting of the California Math Council (Northern Section.) Once again, I had a great day at Asilomar, a beautiful spot near Monterey, right on the Pacific Ocean. Here is my annual report. Conic Sections Figuring out an approach to… Continue reading Asilomar Report: Conic Sections
Remembering Lew Douglas
(Post updated on 19 Jan 2020.) The Bay Area Math Project and the Alameda Contra Costa County Math Educators presented Lessons from Lew, a professional development session in memory of Lew Douglas, a leading Bay Area math educator who passed away in April. Lew delighted in math and developed lessons to allow others to share in that wonder. We… Continue reading Remembering Lew Douglas
Learning from Teaching (cont.)
For the second time this summer, I taught a version of my Visual Algebra workshop, this time as part of a summer institute at the Atrium School near Boston. (Earlier in the summer, I did this at Synapse School, in Silicon Valley, and wrote about it here.) Once again, I walked away from the workshop… Continue reading Learning from Teaching (cont.)
Asilomar Notes: Tech
It is widely agreed among its attendees that the Asilomar meeting of the California Math Council is the best math teacher conference anywhere. Certainly, the setting is beautiful. Over the decades, I have attended some great talks there, and this year was no exception. I will post some notes and reactions here, starting with two tech-oriented talks I… Continue reading Asilomar Notes: Tech
More Catchphrases
Last summer, I wrote a post about catchphrases for math teachers. Some of those were created by other people, but most were my own. It was a fun way to think about what ideas I consider important enough to summarize in a hopefully memorable slogan. Since then, I have remembered three more of my mantras, which are mostly aimed… Continue reading More Catchphrases
