## 3.1415 Celebrate Pi Day!

Pi Day is coming soon! All around the world pi day will be celebrated!

Pi (?) is the ratio of a circle’s circumference to its diameter. To honor this never ending number, people all over the world celebrate it!
When? March 14, 2015
March (3rd month) 14 (day) 15 (year) = 3.1415
The Exploratorium in San Francisco originated the celebration of Pi Day and there are lots of activities scheduled there for their celebration. You can visit their website at http://www.exploratorium.edu/pi/ to find activities for your own celebration! Here is one activity from their website that I thought was fun:
Materials:
Internet access
To Do and Notice:
Pick a number sequence that’s special to you—perhaps your birth date.
Go to the Pi-Search Page and type your sequence in the search box at the top of the page. This web site will search the first 200 million digits of pi in a fraction of a second. (See “How it works” on the Pi-Search Page to find out how this is accomplished.) If it finds your sequence, it will tell you at what position in pi your sequence begins and will display your sequence along with surrounding digits.
No result? Try another sequence. The shorter the sequence, the better the odds of finding it.

I’m sending you an infinite number of smiles for your celebration!

## Number or Numeral?

Which to use? A numeral or a number? What’s the difference?
Well, a numeral is a name or a symbol. For instance, we talk about the numbers using the numerals 3 or the word three. The number is the idea or amount and the numeral is what we write.
But when we are writing an essay, story, or report, how do we know whether to write the numeral or the word? Well there happens to be a rule about it! We follow the rule to spell out single-digit whole numbers such as one, two, six, or nine. Use numerals for numbers greater than nine such as 35, 42, or 180.
