Odd is as odd does …

today’s an Odd Day
this five, seven and nine day
an odd and rare day
we’ve two years ’til the next day
and there’s nothing else to say

Ok, so that was silly.  I discovered that today is one of only 5 days of its kind, and that these days only come around every 100 years.  An “Odd Day” when the date is three consecutive odd numbers: 5/7/9.  The last time this particular odd day happened, was in 1909.  I was charmed by this.  Yes, there are also “Even Days” but there are more of them, so they aren’t quite as exciting.  And, too, my birthday is one of these days and will be again in 4 years: 9/11/13.  Dig that.

So I made this completely unimportant discovery while looking for something else during break tonight, and it fit so well with the conversation we’d been having about the skill of pattern recognition (as we continue studying right and left brain dominance), so I went into class after break and wrote the list on the board (1/3/5 and 3/5/7 and 5/7/9 and 7/9/11 and 9/11/13) and let them have at it.  They came up with a few patterns I hadn’t thought of and then figured out the consecutive-odd-numbers bit.   They were pleased with themselves for doing it, but definitely not charmed the way I was.
