Happy Square Root Day
Square Root Day occurs only nine times per century, and one of them is today: 3/3/09. You might have been busy celebrating New Year’s Day on the first Square Root Day of the century: 1/1/01, and you might have been distracted by Groundhog Day on 2/2/04, but make sure you don’t miss this one, or you’ll have to wait another 7 years until the next one on 4/4/16. 🙂
Since we won’t be in school for Pi Day (3/14), which falls on a Saturday this year, you might want to mention this one to your classes, if you read about it in time.
Happy Square Root Day!
