The Other Math Day

If you have read the previous post, you know about some math days. But there are others.
Today, for example. Today is Count-By-3s Day: 3/6/09.
When we were walking to school, Shelley, my mom, and I were talking about today, the math day. Shelley said that March was a good month for math days.
March also brings a birthday in the family. My sister is turning 5. 5 times 5 equals 10. That could be another math day: 5/5/10. And just next year, too!

My little sister has a blog. To read it, click here.

Math Days

Happy Square Day! **
It's Square Day because the date is 3/3/09. And 3 times 3 = 09. *
More math days:

• Pi Day, where the date is the first digits of pi (3.14159....)... on the day six years after Friday the 14th.

Any more? If you have an idea of another math day, you can comment on this post.

* Next Square Day is on 4/4/16.
