Happy Square Root Day!

Did you know that today, April 4, 2016, is the fourth Square Root Day of the century?

What is Square Root Day?

Square Root Day is an unofficial holiday celebrated on days when both the day of the month, and the month itself, are the square root of the last two digits of the year.

Founded by American high school teacher, Ron Gordon, the first Square Root day was celebrated on September 9, 1981.  

There are only nine Square Root Days in a century, with the final Square Root Day of the century falling on September 9, 2081.


Kids have fun with Square Root Day at The Learning Lab! 

To celebrate this calendar quirk, our Math students will each receive an infographic detailing the related concepts, ‘Squaring’ and ‘Square Roots’.

For our younger Math students, we have simplified the concept of square roots by incorporating the use of a division ladder and Prime Factorisation, a useful method to break a bigger number into the product of prime numbers.


Do celebrate wisely – the next Square Root Day falls on May 5, 2025!
