This one I got online a while ago (http://www.shamplade.com/store_ver02/foil.html) and would wear a lot when I was teaching math.
The funny thing is, I was sick the week in 8th grade algebra that the F.O.I.L. method was taught. I was not able to catch up before the semester was over, and I got my first D ever on a report card. After sacrificing precious after school time (watching hair metal videos and intramural floor hockey games), Mr. Passler was able to help me get back on track. I got an A+ the last quarter. I wonder what he would think of me actually teaching this stuff AND wearing this shirt as I did.
Years later, as a special ed math teacher, I wore this shirt into work one day. Although I thought as usual it would amuse the students, I forgot that for some of them it was an MCAS testing day…woops! I’m not sure if there are official rules for what test administrators can wear, but I don’t think the fate of the students passing or failing was determined by my F.O.I.L. shirt.
If you are “Feeling Like a Nerd” (which is the hilarious interpretation my younger sister had of Bon Jovi’s “In and Out of Love”…sorry Meg!), here are some algebra puzzle sights:
