#anyqs

I was working with Wisconsin’s math teachers this afternoon, making the case that good storytelling is a first cousin to good math instruction. I challenged them at the end:

Give yourself one photo or one minute of video to tell a mathematical story so perplexing that all of your students will want to know the ending, without you saying a word or lifting a finger.

I’m talking about photos and video that provoke a vast majority of your class to wonder the same question without any explicit prompting. For instance, minutes before the presentation began, I tweeted:

Dear Twitter: what’s the first question that comes to mind? http://vimeo.com/23242866 #anyqs

In the last minutes of my presentation – nervous as hell – I showed the group my Twitter feed. Here’s what we saw:

This kind of user feedback is invaluable. The results are mixed. There is a degree of consensus around one question but I still may head back to the drawing board to reshoot the problem in a way that makes “How many are there?” the most natural, perplexing question to ask.

So I’m pitching the same challenge to you. I have my hawk eyes on the #anyqs hashtag and I can promise you’ll get a question from me, at the very least.

PS:

You know which group of students seriously doesn’t hate it when you pose intriguing mathematical questions without words? English language learners. I know it’s some kind of cliché to say that a picture is worth a thousand words, but seriously: the more scene-setting you can embed in a photo or video the better for everybody.

PPS:

Consider how bizarre the #anyqs challenge would appear to your textbook’s publisher. They work in a world where it’s totally normal to take some cheap clip art or stock photography and ask a question about it that would occur naturally to nobody else in the world. I’m challenging you to flip every aspect of that around.

Truth In Advertising

This is my favorite brand of pita chip – no contest. I lose myself for hours staring at the bag. It’s like, “Wait. What? You’re telling me eight is 33% more than six? Bigger bags have more chips?!

A Phrase I Try To Avoid, Ctd.

Batnastard:

I have found that when I pose an interesting, accessible problem, abstract or concrete, the students get completely absorbed and forget themselves, and never ask “when will I use this.”

When students ask that question, nine times out of ten they aren’t really asking that question.

A Phrase I Try To Avoid

I understand what it means. I know it’s code for something that basically everybody understands. But I’m not comfortable with the implication that if the mathematics won’t help you build a deck or make payroll or beat the odds at a card table that it’s “fake-world math” (or, even more unfortunately, “fake math“) and without value. Mathematics, as it’s studied by mathematicians, is challenging and satisfying work that’s accessible to anyone with a pencil, some scratch paper, and a curious mind.

I’m happy to work in this niche, with these “applications of math to the world outside the math classroom.” It’s important that when our students ask if mathematics has any practical or explanatory power in their lived experience that we can answer “yes” without our assigned curriculum undermining us. And if it’s printed on paper, there are a number of ways it’s doing exactly that.

I have some leverage here and I’m happy for the opportunity to help out with this problem. But I’m not confused that it’s the only problem.

Dissent Of The Day: H. Wells Wulsin

H. Wells Wulsin:

I recognize that I am probably not going to persuade you (or most of your readers) on this point. But these kinds of strategies have never been tried before in a math software package, and if they do work, then the developers stand to make a lot of money, and it could help a lot of students. I can’t be sure how effective these strategies would be until they’re tried, but I have a lot of reasons (which I tried to explain in the article) to think that they have the potential to make a big difference. That’s why I’d like to see a publisher or software company invest a few million dollars to produce a really high-quality software product.
