This is the first time in 26 years that I haven’t been able to observe a weekday Pi Day with any of my classes. Sigh. But there are plenty of online resources for my past, present, and future students.

## Weston’s 17th Fractal Fair

I returned to Weston yesterday for its 17th annual Fractal Fair. That’s a lot of fractal fairs! As you might expect for a subject that keeps evolving every year, with an entirely new set of exhibitors every year, the fair… Read More ›

## How many Tater Tots? — the answer!

Yesterday I posted this problem: Great Fermi problem that I just heard on the Ask Me Another quiz show on NPR: Estimate how many Tater Tots were consumed in the U.S. during all of 2017. The answer (from CBS News)… Read More ›

## How many Tater Tots?

Great Fermi problem that I just heard on the Ask Me Another quiz show on NPR: Estimate how many Tater Tots were consumed in the U.S. during all of 2017. Correct answer will be posted in this space tomorrow.

## Computational thinking — but where’s the beef?

Do we believe what the Wolfram Blog says about computational thinking? Maybe. I’m suspicious of the very title of the post: The Computational Classroom: Easy Ways to Introduce Computational Thinking into Your Lessons. Anything that promises “easy ways” is automatically… Read More ›

## Moral hazard?

“You learn something new every day of your life,” my dad used to say to me. He was right, of course. A week ago I learned a concept that is, apparently, familiar to economists and philosophers but was for some… Read More ›

## “We don’t work with greasy machines!”

“In the Mathematics Department we don’t work with greasy machines,” replied one of my undergraduate math professors with a sneer. “You’re going to have to go to the Applied Math department if that’s what you want to do.” That was… Read More ›

## Feedback from 46 years ago

Going through some old papers, I came across a summary of student feedback from Relations & Functions, a course I team-taught at Lincoln-Sudbury (L–S). This was more-or-less equivalent to today’s Honors Precalculus, and it’s instructive to consider the similarities and… Read More ›

## Awesome!

I can’t help keeping track. Four restaurant meals ago, at the Menotomy Grill, our young server said “Awesome!” four times during our meal. I foolishly thought that would be some kind of record. Lower Mills Tavern was better: just two… Read More ›

## How to succeed in high-school math by paying attention to stereotypes.

At the high-school level, a student can’t be expected to understand the concepts behind the math; you’re just expected to be able to do the math. So says a commenter from Old Field, NY, objecting to a wonderful article in… Read More ›
