It is not uncommon for would-be curriculum reformers to decry the fact that our schools are organized in different disciplines, and thus different departments. This affects not only curriculum, but…| Henri's Math Education Blog
On BlueSky, Bryan Meyer asks: Henri, in your experience, what are the pros and cons of using function diagrams with kids (in addition to the more standard Cartesian representation)? My BlueSk…| Henri's Math Education Blog
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→| Henri's Math Education Blog
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→| Henri's Math Education Blog
Proof in Geometry Many years ago, when I was still teaching high school, I added a Teaching Proof page to my website, which included a bit of philosophizing and links to the relevant parts of the site. If you’re looking for ideas and materials on this topic, you should definitely check out that page. I’ve… Continue reading Proof in High School→| Henri's Math Education Blog
You can now preorder my new book, There Is No One Way to Teach Math (co-authored with Robin Pemantle). I wrote about it in my previous post, where I forgot to mention that I link to many resources …| Henri's Math Education Blog
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!→| Henri's Math Education Blog
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 schoo…| Henri's Math Education Blog

In early December, I attended the California Math Council Northern Section conference in Asilomar, as I’ve done almost every year since the mid-1980’s. In my last post, I discussed my session on fr…| Henri's Math Education Blog
Last weekend, I shared my thoughts about teaching fractions with teachers of grades 3-5 at the Asilomar meeting of the California Math Council. After decades of work in high school, and hundreds of…| Henri's Math Education Blog
Learning Tools In 1981, after ten years in K-5, I switched to teaching high school math. In some ways, this felt like starting a whole new career: the math was more involved, the relationship with …| Henri's Math Education Blog
At some point, maybe thirty years ago, it became fashionable to emphasize functions and their multiple representations in secondary school math. This was in part driven by the newly available elect…| Henri's Math Education Blog
