Today, another guest post, this time from a homeschooling mom. -- Henri Algebra and Geometry Greetings! I hope this email finds you well. I know you don’t know us, but I wanted to personally thank you for your math books. I cannot express how helpful your books have been, and the relief I have… Continue reading Letter from a Homeschooling Mom

Mentoring and Coaching
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
Asilomar Report 2024
I hadn’t planned on attending the Asilomar conference this year, as both my proposed presentations had been rejected. However I was on the waiting list, and was invited at the last minute, presumably because there was a cancellation. Once again, it was a smaller conference than pre-Covid, and I saw fewer familiar faces among the… Continue reading Asilomar Report 2024
Making Struggle Productive
At the start of the opening chapter of our new book (There Is No One Way to Teach Math), Robin Pemantle and I argue that teachers should learn to embrace contraries. The idea is that instead of choosing one or another option in a binary pedagogical choice, and instead of seeking a supposedly happy medium… Continue reading Making Struggle Productive

There Is No One Way!
This is the cover of my upcoming book about math pedagogy. Art teacher / artist Briana Loewinsohn created the image, based on this photo I came across ages ago: “There is no one way” has long been the slogan for my website and blog. It was inspired by the story of the zen master who… Continue reading There Is No One Way!
Working with Pentominoes
This is an update of a post from 2013, when Didax published my book Working with Pentominoes. You can still buy the book. It is geared to grades 4-8, though I used some of the content in high school. Pentominoes are a geometric puzzle, a staple of recreational mathematics. This is what they look like:… Continue reading Working with Pentominoes
Geometry Labs Notes
In this post, I share thoughts about my Geometry Labs (free download), and complement some of Mimi Yang's notes about it. (In fact, this post was suggested by the existence of Mimi’s notes. You may find those useful, as she lists which topics are supported by various labs.) First, big-picture thoughts. The book includes obviously… Continue reading Geometry Labs Notes
Supertangrams
Many years ago, in the exhibits area at an NCTM national meeting (in New Orleans?), I saw math teachers standing in an insanely long line. I had never seen anything like it, and never saw anything like it since. They were waiting to have a book signed by Martin Gardner, the author of the “Mathematical… Continue reading Supertangrams
Convex Tangram Polygons
If you’re a regular reader of this blog, or visitor to my website, you probably know of my long-standing interest in geometric puzzles. Among those, tangrams are probably the most well-known and widely available. Thus I included them in Geometry Labs (free download) where they are the subject of Section 2, and Lab 10.6. In this… Continue reading Convex Tangram Polygons
