The Triangle Problem(and more)

The math club posted the triangle problem on community-comments. See if you can solve it. Solve more below! Thanks to all who joined the discussion!




Something I’m Working On…

Sent on by a non-math teacher, I was introduced to the Coursera program Introduction to Mathematical Thinking. It’s going to be my personal challenge for the next couple of weeks as it battles for its place among school work, AMC test prep, Project Week planning, etc. It’s an exciting possibility, and I will definitely write more on the results once it’s done!

The “teacher” is Keith Devlin (who I heard this awesome talk from here – thanks Libby!). This talk is a great introduction to his way of thinking, which I’m hoping I will get to explore more of in the next couple of weeks. 

Have a great day!


The Desmos Challenge

The very first activity our math club did was a Desmos challenge. Desmos is an online graphing calculator, which we use in our math classes. Our teachers introduced it to us, and we found it very easy to use, and can create very beautiful graphs, sometimes accidentally. Since we have many artists in Putney, in November, immediately after the math club is formed, we came up with this idea, and presented to the school “The Desmos Challenge”. It was a simple competition, that whoever makes the most beautiful desmos graph wins a prize. It had effects we did not anticipate, such as it inspired math teachers to have their students make beautiful graphs for homework. In January, the challenge ended with Erin as winner, winning a Sudoku keychain.

Excelling at math- skill or practice?

Hi all, 

Derek’s last post reminded me of this article, which my mom sent on to me several months ago. We are so accustomed to hearing people say, “I’m just not a math person,” and while that may be true, there are many variables in the way of that declaration that so many people make without thinking. This article is fascinating, and worth a read if you have the time. 

There’s one key difference between kids who excel at math and those who don’t

Enjoy! (Though I would not advise going on rants at people who say, “I’m not a math person” after reading this article, as that strategy is not especially effective for getting those people to actually like math. I’d try the Mandelbrot set instead.)


The Start

When I talked to my friends about math, I found that some of them believe that you need a different kind of brain to be good at math. But this isn’t what I was told when I grew up in China. People do not believe in talent or gift, but in endeavors. If someone is better at math than you, it is only because that person spends more time practicing it, and you need to spend even more time to catch up. “You have to practice every day, or your brain would rust,” says our math teacher.

When I proposed a math club in Putney, I have both views in mind. Math is not only about practice, it is a joy. I hope that math-lovers can enjoy math together. At the same time, more people can get interested in math.

This is how the math club started at Putney.
