You can breathe a sigh of relief because ‘Wedgies 2.0’ is not in the current curriculum. This is merely an ad campaign for a middle school program called “Digits.”
The ad states “A middle school program opening minds to math and science. Figure this. Imagine that.” in the bottom right corner with unlikely subjects chalked above including cloning a girlfriend and even a formula for invisibility to become a spy.
The advertising agency behind this campaign is Arnold. I must say that they did a pretty good job. I love the artistic chalk art!
