Math Links for Week Ending Mar. 17th, 2017

I have loved Desmos Activity builder since it came out. Over the last year or so I have taken a stab at creating a bunch of these. They run the gamut of some geometry stuff from grade 6 to Calculus and in between. Try them out and let me know if you see room for improvement.

I love when things are made visual (and interactive). This site does both, although some of the concepts go beyond elementary and secondary math, there is enough here that you can still find something to bring statistics to life for your kids. Thanks to @Sharon_Drummond for this one.

How about a fun clock that requires you do do math (order of operations) to tell the time? Thanks to @kMarkPet for this one.

It was PiDay this week. You can see all of my Pi related links on my PiDay Pinterest board here. Here's a few more. This one from Science Friday.

I made this video to explain how to make your own Desmos Marbleslides.

My daughter pointed these out to me. They are a series of videos where they survey 100 people (usually they were made of demographically diverse groups) about various topics and ask them to choose yes or no by stepping into a circle. A lot of the questions are US centric (but not all). But you might be able to use them to talk about surveying and bias. Click on the link below for all of the videos in the first season.

I love this video from @standupmaths where he approximates Pi by randomly rolling two 120 side dice 500 times and breaking them up into numbers that have cofactors and those that don't (and if you want here's the 2hrs of raw footage). You could easily repeat this in a class and wrap it around the idea of factors of numbers. So good.

Here's a video for PiDay on why Pi is important. As if we need to know.

Although they admitted to this being Photoshopped, it's still nicely done.

If you wanted you cold have run a virtual 5km race on Pi Day. I guess that means you register and pledge to run 5km on PiDay and they send you a medal. At least the medal is very cool. Thanks @Robin_Grondin for this one.

And finally a Pi related question with what has a surprising (at least to me) result. Thanks to @Esping_math for this one.
