Math Links for Week Ending May 22nd, 2020

With all of the data floating around about Covid-19 it's hard to find just the right one to use in your class. Well last week this data showed up all over my Twitter feed and it's a great example of "how to lie with statistics". And just for fun, I took the graph and re arranged it to chronological order. Since then the Georgia officials have walked it back. But still it's a great example to open discussions with your students.

What do you notice & wonder? I saw this graph (now corrected) & couldn’t help but think about the meaningful discussions to be had in a math class. Data Literacy is a critical skill our Ss need in order to make sense of the world. #mtbos #iteachmath #forsythpln #learningtransfer pic.twitter.com/JJQfz0L9Sd

If you are looking for something for you (or your students) to do while we are learning from home, I strongly suggest @Anniek_P's daily #MathArt challenges. As I type this, she is at Day 66. They are for humans who have all levels of artistic and mathematical ability. Check them out

The Nine-Point Circle

Construct a circle through the midpoints of the three sides of a triangle.

This circle also passes through the foot of each altitude and the midpoints of the line segments from each vertex to the point where the altitudes meet.https://t.co/pHyJhOgu7A pic.twitter.com/XuWAtBBhJA

This infinite series was used by Archimedes circa 250–200 BC.
It's a geometric series with first term 1/4 and common ratio 1/4.#iteachmath#mtbos #mtmschat#maths pic.twitter.com/kAwSi7Ynbx
