There is a new open letter by STEM practitioners who oppose the California Math Framework revision (CMFR). The same group also published an Analysis and Critique of the proposed changes, and a blog post by Boaz Barak and Edith Cohen. I’ll use the latter's initials (BB/EC) to refer to them and the set of three… Continue reading Yet More on the California Framework (Part 1)

Asilomar report, 2021
I attended the California Math Council North’s conference in Asilomar last weekend. Because of Covid, it was a dramatically smaller conference than usual. As a consequence, there were fewer sessions to choose from, and probably a smaller turnout for many of them. Here is my nearly annual report. Python Turtle Ned Diamond presented the Python… Continue reading Asilomar report, 2021
Detracking, How To
This is my third post on the in-process revision of the California Math Framework. If you haven’t yet, please read the first two: The California Math Framework Revision, and More on the California Framework. I just reread them, and find that I stand by what I wrote: the revision attempts to address an important issue: low-track… Continue reading Detracking, How To
More on the California Framework
The Independent Institute published an Open Letter to Governor Newsom, calling for the complete abandonment of the (currently in progress) revision of the California Math Framework. Before I share my thoughts about the letter, I will ask you to please make sure you read a previous post, in which I commented on the current draft… Continue reading More on the California Framework
Geometric Puzzles Unit
—————————————————————————————————————— I added links to this post, updated it, and uploaded it to my website. Read it there! —————————————————————————————————————— The Geometric Puzzles home page on my website contains many links, and it is organized reasonably well. Still, someone who is not familiar with all these puzzles may need help in turning them into a… Continue reading Geometric Puzzles Unit
The Game of Pent
Puzzles are a big part of my work as a teacher and curriculum developer, as you can see in this article, in the Geometric Puzzles launch page on my website, and in fact throughout my books. (Not to mention my parallel career of sorts as a cryptic crosswords constructor, and how I spend much of my free time.)… Continue reading The Game of Pent
Integrating the High School Math Curriculum
The standard middle school / high school course sequence in much of the US is Pre-Algebra, Algebra 1, Geometry, Algebra 2, Precalculus. This is pretty much a US-only concept: elsewhere, algebra and geometry are taught every year in middle school and high school. This American tradition leads to many endemic problems: The traditional Algebra 1 includes an enormous amount of… Continue reading Integrating the High School Math Curriculum
The California Math Framework Revision
California is revising its Math Framework. A draft has been updated after a first round of public comments, and a second round will take place starting in December. The Framework is of course an important document that will affect math instruction in public schools throughout the state for at least several years. I have not seen… Continue reading The California Math Framework Revision
Commitments
In a blog post seven years ago, I summarized “Embracing Contraries in the Teaching Process”, an important article by English professor Peter Elbow. In that post, and its sequel, I tried to apply Elbow’s ideas to the teaching of math. I encourage you to read both posts, and Elbow’s article (which I linked to in the first… Continue reading Commitments
Fraction Rectangles
This is a sequel to my last post (Seeing is Believing?), addressing the same issue from a different point of view. Fractions, of course, are difficult. When teaching 4th and 5th grade in the 1970's I struggled with this, and came up with a powerful learning tool: fraction rectangles. The idea is that it is… Continue reading Fraction Rectangles
