This, Dan Meyer says, is how too many students experience mathematics. Meyer, 33, is perhaps the most famous math educator in America today. Good-looking and wholesome, he has long charmed audiences with a lopsided smile. He’s amassed more than 40,000 Twitter followers, and his TED Talk, despite its less-than-thrilling focus on math curricula, has been viewed more than two million times. Meyer’s out to change the way students learn math—to make the subject feel like an illuminating journey through the real world, rather than an abduction into an alien culture.
