Math Links for Week Ending Mar. 24th, 2017

I'm getting caught up on a lot of blog posts lately and the Desmos crew have been busy. Some neat little activities have been released over the last few weeks. You can practice working with angles in this laser/mirror simulation. Practice with linear functions (kind of like Central Park) by starting with estimation. Do some exponential decay by bouncing balls. And more linear expressions with this interactive border problem.

A few weeks ago I posted Dan Finkel's TED talk about being a math teacher. It featured a really cool factor model. It turns out I missed this other factor model that @dpscher featured another cool model and added some interactives and a how to video to go along with it.

Here's a really cool interactive from @EmathsUK on rates of change where you have to create your own custom flask and then guess what the filling profile will look like. It's different version of this classic question than Desmos' Waterline but still a great activity.

I like this combination Google slides primer and how to develop thinking in a math classroom from @alicekeeler. I really like the idea of showing the thinking process including all of the mistakes. Take a look

Some leftovers from PiDay. This one from @mathequalslove giving us this geometric puzzle

Another PiDay leftover from @rjallain. This time by using a random walk. He goes into all the detail with algorithms and the graphical analysis.

And the last leftover from PiDay comes from the Physics Girl and Veritasium. Here they calculate Pi by throwing darts at a target. Again, more randomness. Watch the video at the link below

It all starts with counting. Before we can do any math we have to count. That is part of the premiss of the book "Numbers and the Making of Us: Counting and the Course of Human Cultures" from Caleb Everett. Here is an interview with the author about the topic.

Here is a nice interview with @mathletepearce from @DerekRhodenizer on the current state of math teaching. I liked the bit about if you were in a home where your parents yelled, then likely you will be a yelling parent until you become mindful of how to break that pattern. For many of us that's what teaching is. We teach how we were taught until we see a better way

I like this visualization from @mathletepearce on visualizing x/6 = 2

A new @numberphile video on Pascal's Triangle. Even though many of the patterns mentioned I knew of there were a few tidbits that I hadn't.

And another one from @numberphile on the four colour theorem. I love the four colour theorem and especially because it's proof marked the beginning mathematical proofs via computer.

A new TED talk from @JoeBoaler on mathematical mindsets
Curriculum Tags: All

An interview by @Anthony_Bonato with @JSEllenberg who wrote the book "How Not To Be Wrong: The Power of Mathematical Thinking" and if you want you can watch this talk from a couple of years ago

The Giant's Causway is a fabulous example of how nature has many strange secrets. So cool that these hexagonal rock formations were create naturally. Check out all the pictures at the link below.

Who knew there were so many types of quadrilaterals

Here's a neat visualization of the top 100 websites currently

Here's a few more images left over from Pi Day
