In a presentation filmed at a locally organized TEDx conference in Costa Mesa, Calif., last month, former Los Angeles teacher Nigel Nisbet explains how he turned chocolate bars into geometry pr... to get kids hooked on math.
Nisbet says he spent his first few years as a teacher struggling to engage students who "had switched off to math." While standing in a supermarket checkout line, it hit him that he might be able to capture students' interest by creating problems based on more relatable (and even universally loved) topics—such as chocolate. He then picked up several chocolate bars in the Toblerone-style packaging and devised a lesson around a single question: "Why make a chocolate bar in the shape of a triangular prism?"
