This also comes in handy when a student inevitably asks "So, what does a set look like if a small standard deviation exists?"
So, why the subtle differences among the images? My first year of teaching, I knew staff ID photos would be taken, but wanted to wear something comfortable for the back-to-school staff inservices. Blue striped polo? Perfect.
The following year, I overlooked the previous year's ID shirt and coincidentally wore the same shirt as the previous year. 2-for-2? Cool.
My third year of teaching, my wife coerced me into wearing something different, citing that "people will think I don't know how to do laundry if you wear the same shirt all the time." Eh. What's one year in a different shirt hurt? I'd still get inducted into the Hall of Fame with a .667 average.
And so it went, year after year, reverting to Old Blue for staff ID photo day. Granted, this #Made4Math project took some time to accumulate the punchline, but has been a fun tradition for my students to cheer me on from year to year, almost like a recurring inside joke they are part of.
Funnier still is the fact the shirt still fits, and that it hasn't worn out. But, I guess that's what you can expect when it only gets worn once a year.
I know this post isn't very creative or insightful, but hopefully it is good enough for a light chuckle at my expense. Laugh it up.
