I originally wrote this four years ago for work. I’ve updated the years (“29 years ago” instead of “25 years ago”) but it’s otherwise a straight lift from then. Also: starting at 10:30 AM today, I have a dozen or so tweets about Square One scheduled, in case you want to follow me on Twitter.

Twenty-five years ago today, my life changed for the better. Twenty-five years ago today, Square One TV debuted.

Square One was a thirty minute delight featuring short sketches about math. There was Mathman, a math-parody of Pac-Man, who would go around the game board looking for tasty numbers to eat — but only ones which met the rule of the day. (Fans of the show can probably hear the voice in their head: “Mathman, Mathman, multiples of three, multiples of three, Mathman.”) The show had miniature game shows, likePiece of the Pie and But Who’s Adding?, featuring regular children as contestants. It had math-teaching music videos like Nine, Nine, Nine (“times any number you can find, it all comes back to nine”) and Less Than Zero (“a certified, nationwide klutz”). There was Dirk Niblick, Blackstone, Mathcourt, and more.

And of course — of course! — there was MathNet, which closed every episode with a piece of a week-long story. Be it the kidnapping of Steve Stringbean or the complicated confidence scam perpetuated by the mysterious swami, these MathNet memories are ingrained deep in my psyche. Trying to figure out how George Frankly and Kate Monday (or Pat Tuesday!) would solve the case became an obsession; tuning in on Friday to have the answer revealed became a core part of my week.

It was math. And it was wonderful.

The nine year old me did not know it at the time, but like everything else we do at Sesame Workshop, Square One was designed to address an educational need of children. In this case, Square One‘s goal was to address the “math crisis” of eight to 12 year olds in the United States, using media to help teach mathematical concepts in an enjoyable fashion. And while writing this blog post for the organization which created the show appears self-serving, if you’ve spoken to me about Square One, you know that I can still sing significant parts of 8% Percent of My Love (and have also reserved 10% of my love for the New York Football Giants; sorry Patriots fans) while reciting esoteric plot points from series of MathNet. Does anyone else remember the kid who tried to sell George the $50,000 pencil? He only needed to sell one!

Happy birthday, Square One TV. And may you avoid Mr. Glitch.
