Through Math for America, I am part of an on-going collaboration with the New York Times Learning Network. My latest contribution, a Test Yourself quiz-question, can be found here:

This question is about the costs of providing educational technologies, such as the math software Cognitive Tutor, to students in the United States.
This is a fun slideshow of images from architect George Legendre’s book “Pasta by Design”

The slideshow, from the on-line New York Times Style magazine, shows a few different renderings of pasta shapes. The book, apparently, contains actual cooking directions as well as these technical schematics.
It appears as though Legendre used a graphing utility like Mathematica or Maple to sketch out his pastas. A creative, and fun, application of this technology!
This is a great resource: a brief history of many mathematical symbols.

Ever wonder where the symbol for 
There’s all that, and much more! Although, I would like to know more about the bar used to represent repeating decimals.
Preparing a Sunday brunch, I unconsciously turn bacon into tangrams.
There are a lot of trapezoids among these bac-o-grams!
This is a great resource: an archive of Problems of the Week from MathCounts.org.
https://mathcounts.org/Page.aspx?pid=1573
MathCounts is a national math enrichment organization that, among other endeavors, runs a middle school math competition every year. Their “Problem of the Week” is typically aimed at middle school students, but these problems may also be of interest to high school students and teachers.
There are over 10 years of math problems in the above archive. The problems range in scope from basic “Math Team” style questions to thematic questions based on current events, dates, and holidays.
