A Round-up of Pi Day Resources

Pi Day is on Tuesday. Last week I shared a few resources for teaching and learning about pi. This post is a summary of those resources and a few more.

OPEN Phys Ed offers five free physical education lesson plans centered around Pi Day. The lesson plans are designed to be used in elementary school and middle school. The five Pi Day lesson plans offered by OPEN are:

Pi Toss
Pi Day Races
Pi Day Dice Relay
Cake or Pi?
Who Wants Pi?

To access the lesson plans you do need to register for a free OPEN Phys Ed account. Once you have an account you can download the lesson plans for free as PDFs and Word documents.

On Drawings Of... Lillie Marshall is offering three free printable coloring pages for Pi Day. The first is a visual explanation from the "Pi Queen" and the other two are sheets of little pi-themed cards that students can color and give to each other. Get the Pi Day printables here.

Numberphile has a few good videos about pi and Pi Day. Pi with real pies is a three minutes and fourteen seconds video that explains Pi and how it can be calculated.

After showing the video above, you might want to follow up with this video, How Pi Was Nearly Changed to 3.2.

A Mile of Pi, as you might guess, is about a mile of digits.

Exploratorium's Science Snacks site has three hands-on activities that you can do on Pi Day (or any other day of the year).

Pi Toss is an activity in which students toss tooth picks is a physical recreation of Buffon's Needle Problem.
Pi Graph is an activity in which students graph the diameter and circumference of a series of objects in order to see the linear relationship between any circle’s diameter and circumference.
Cutting Pi is an activity in which students use string to measure the circumference of an object and then attempt to cut the diameter of the object from the string as many times as possible. In other words, it's a physical way to divide the circumference by the diameter.

Tynker is a service that offers programming lessons for elementary school and middle school students. For Pi Day Tynker has a free lesson plan in which students practice their programming skills by making art based on Pi. The free lesson plan has students use Tynker's block programming interface to create art and animations featuring the digits of Pi.

Pi Skyline is an art project that has a Pi Day theme. In the project students shade graph paper to correspond to the digits in pi. Then they cut out the graph and place it on a shaded background to create a city skyline effect. Watch this one minute video to see how the project comes together.

Finally, if you want to give your students a Pi Day ear worm, play the Pi Day Song for them.

The Nationwide Legal DMCA Scam Returns - There's a Lesson Here

On a few occasions last year I wrote about a scam in which someone who pretends to be an attorney from a law firm called Nationwide Legal or Arthur Davidson Legal sends an email stating that a website owner has committed a copyright violation. The recourse that they seek is a link to another website for credit for the image. All of the details of the scam can be read here, here, and here. All that to say, the scam is back!

On Friday morning I got an email from someone claiming to be Victoria Boyd, Trademark Attorney at Nationwide Legal. It's the same scam as before. The difference is that now the website for the fake firm is hosted a different domain since the old site was shuttered by the hosting service. The pictures are the same, the typos are the same, the nonsensical logic is the same, and the scam is the same.

Lessons for Everyone

1. Don't be a lame SEO backlink scammer.

2. If you do get an email from someone claiming to be an attorney (or similarly tries to appear authoritative) and it doesn't seem right, look at all of the context clues. In this case there were a lot of context clues that made it fairly obvious that there was a scam at play. The first of those clues being that the email was addressed to "owner of website" and not to any particular person.

3. Don't click on links in emails that you weren't expecting.
