Transit maps TED talk!
I suppose it’s possible that you don’t share my passion for transit maps. That might be hard to believe, but I admit that it’s possible. Whether you love transit maps or not, you still need to watch Aris Ventikidis’s first-rate (and… Read More ›
The Universe in Zero Words
Well…not really zero words…closer to 100,000, in fact. But the main point of Dana Mackenzie’s beautiful book about beautiful mathematics is his combination of illustrations, numbers, and the equations relating those numbers to each other. Essentially, The Universe in Zero… Read More ›
Math Forum
We had an interesting Math Forum last night, sponsored by the PTO (which I understand is called the PTA in some states). This was an opportunity to discuss Weston’s secondary math program in an open forum. Maybe 55-60 parents attended,… Read More ›
A double dose of algebra
An interesting article by Kalena Cortes, Joshua Goodman and Takako Nomi appeared recently in EducationNext, a right-wing magazine that comes out of Stanford’s Hoover Institute. They claim to be fair and balanced. Sound familiar? Those aren’t their words, actually, but that’s definitely their gist:… Read More ›
The Dead Puppy Theorem
(a + b)2 = a2 + b2. Right? “No, of course not,” you say. Or maybe you say “Yes, of course.” If you say yes, you’re making the same mistake that 42% of high-school students make. I just invented that statistic on the spot,… Read More ›
Math wins!
This morning’s XKCD:
Fractal pancakes!
Maybe some of my precalculus students will make fractal pancakes for the Fractal Fair in March (though I’m not sure where we could serve them, as the Fair is held in the school library). Here’s what they look like:
Emulating the TI-84
American schools have been using Texas Instruments calculators for more than a quarter of a century now. They have become the de facto standard. More recently, computers and projectors have become ubiquitous, so you would think that we would have a better… Read More ›
The travel(l)ing salesman: a movie?
If you’re into advanced discrete math, you know all about the Traveling (in the U.S.) or Travelling (in other English-speaking countries) Salesman Problem. If you aren’t, you don’t. I won’t attempt to summarize it here; just go read about it… Read More ›
What can goats teach us about problem solving?
A lot of people take their dogs along for a hike…but never before had I heard of taking one’s goats hiking. “What,” you may ask, “does this have to do with math?” Read Dan Finkel’s excellent post. And be particularly… Read More ›
Could it have anything to do with her gender?
I don’t quite know where to begin. It’s not just that a highly respected math educator (a professor at Stanford, no less) has been unfairly attacked by a couple of mathematicians. The shocking thing is that the attacks are so… Read More ›
Honors Geometry opens with a challenging start.
It’s always hard to decide just how challenging the first month of Honors Geometry should be. Last year it was too easy. There were too many students who apparently said to themselves, “This course isn’t so hard.” As a result,… Read More ›
Independent study
Every year there are quite a few students who want to learn more than the regular courses can offer them, so they find a faculty advisor and create an independent study. Sometimes it’s truly created by the student, with the… Read More ›
I'm glad I don't teach in Texas.
The final release of the Texas Republican Party platform includes the following plank: We oppose the teaching of Higher Order Thinking Skills (HOTS) (values clarification), critical thinking skills and similar programs… Since the government of Texas is controlled by the… Read More ›
Is God a Mathematician?
Mario Livio’s Is God a Mathematician? is a first-rate book, so why are there so many negative reviews of it on Amazon? The best answer, I suppose, is that there are always negative reviews on Amazon; any given book can’t be… Read More ›
New England Math Playoffs
Congratulations to the Weston High School Math Team for their strong showing in the New England Math Playoffs! We finished seventh among all the medium-sized high schools in New England. Special congratulations are due to sophomore William Kretschmer, who achieved… Read More ›
Radical Equations and related matters
A couple of years ago I got around to re-reading Radical Equations: Civil Rights from Mississippi to the Algebra Project, by civil-rights activist/math teacher Robert Moses. Just now I realized an interesting resonance with the post I wrote last week about… Read More ›
"Some of our students objectively can’t learn algebra."
No, of course I wasn’t the one who said that. It comes from a petition signed by 14 of Palo Alto High School’s 20 math teachers, listed by name (!) in a blog post by Dan Meyer, who is always… Read More ›
Proofiness
Read this book! Presidential candidates, and anyone who expects to vote for a presidential candidate, should also read this book. Its subtitle explains the Colbertian word of the title…or does it? Oddly enough, the subtitle changed between the first (hardback)… Read More ›
