Are the last two digits of the year a perfect square like 2016? Celebrate 4/4/16 it's the time to celebrate squares or square roots! This day doesn't occur every year but be on the lookout!

Women in Math Celebration

This celebration isn’t set on a fixed date, but usually takes place sometime in the spring in middle and high schools. It is meant to encourage young women to pursue a career in a math or science field. Inspired by Sonia Kovalevsky, an important Russian mathematician and born on January 15,1850. it is a great time to celebrate Women in Math/Science. Other great women in math can be found at: http://www.agnesscott.edu/lriddle/women/alpha.htm

Odd Day

Odd day is a day that singles out those ODD numbers. It occurs when three consecutive odd numbers make up a date– something that happens only six times a century. The last Odd Day was 7/9/11 and the next will be on 9/11/13.

Ben's Oscar Forecast blog -http://oscarforecast.wordpress.com/ - find out how Ben Zauzmer, a Harvard student calculates his predictions and some trivia as well. Are the Oscars predictable? Here's what they're writing about Ben Zauzmer -

The Greek mathematician Archimedes approximated pi by inscribing and circumscribing polygons about a circle and calculating their perimeters. Similarly, the value of pi can be approximated by calculating the areas of inscribed and circumscribed polygons. This activity from NCTM's Illuminations allows for the investigation and comparison of both methods. http://illuminations.nctm.org/Activity.aspx?id=3548

π is a ratio that exists in nature - It is most important that students realize this: know how it is calculated (circumference of a circle/diameter), learn about transcendental numbers, and the mathematical significance of pi. There are all sorts of activities of Pi Day that celebrate its history as well as the silly and sometimes creative activities in classrooms.

Marc A. Umile is known to many as the Pi Guy - In January,2007 the 40-year old from Upper Darby, PA became the North American record-holder for memorizing pi. He made it to the 12,887th digit. http://www.npr.org/templates/story/story.php?storyId=8900845

October

October 10 - Pi-e Day

π in base e (the e of natural logarithms, or the ``other’’ commonly studied math number which exists in nature) begins 10.10..., so that would make Pi-e Day October 10 anywhere. (π in base π= 10.) (http://ccssimath.blogspot.com/2013/03/the-life-of-pi.html)

October 23 - Mole Day

This number is best known to science teachers, especially those teaching Chemistry. The mole, Avagadro’s number (6.02×10^23) that’s used as a basic unit of measure in chemistry. It’s observed on October 23rd from 6:02 am to 6:02 pm, and can include enjoying anything mole related from mole sauce to creating a mole to playing Whack-a-Mole. Seems like puns are celebrated on this day!

Are you a math nerd? Nov. 23 is the celebration of Fibonacci’s sequence. This sequence, made famous by the Italian mathematician, creates a spiral and begins with the numbers 1, 1, 2, 3, so the holiday is celebrated on November 23rd of each year. Celebrate with Fibonacci problems, look at it's applications, and/or enjoy Italian Food.
