Happy Square Root Day!

From Yahoo news:

Dust off the slide rules and recharge the calculators. Square Root Day is upon us.

The math-buffs’ holiday, which only occurs nine times each century, falls on Tuesday — 3/3/09 (for the mathematically challenged, three is the square root of nine).

“These days are like calendar comets, you wait and wait and wait for them, then they brighten up your day — and poof — they’re gone,” said Ron Gordon, a Redwood City teacher who started a contest meant to get people excited about the event.

Be sure to get your fill of square carrots and radishes, there are only 6 left in this century:

1/1/01
2/2/04
3/3/09
4/4/16
5/5/25
6/6/36
7/7/49
8/8/64
9/9/81

World Maths Day 2009

wmd_logo_maths_m

This annual event will be held on March 4th, 2009 and will last as long as it is March 4th somewhere in the world. From the World Maths Day website:

Unite with students and schools from around the world to set a new world record! The Challenge – to correctly answer more than 182,445,169 questions in 48 hours.

Students play against each other in real time playing mental math games.  Each game lasts for 60 seconds, students can play as many games as they wish. The questions are appropriately leveled for different ages and abilities and cover basic math facts. Of course, this is a free program, but time to register is running short. Teachers register their teams and are provided with a unique login and password for each student. When students login, they watch on a map as they are connected with students around the world to compete against.

Have fun and keep an eye out for students from a certain Math Club in Colorado.
