Don’t Lose the Mathematics

Room to Grow - a Math Podcast

In this episode of Room to Grow, Joanie and Curtis talk about teaching strategies for remembering in mathematics, such as mnemonic devices, tricks, and gimmicks.
They challenge the notion that teaching with tricks is inherently bad, and discuss how to determine when a strategy intended to help students learn might actually work against their understanding of the underlying mathematics. For instance, “FOIL” and “SOH-CAH-TOA” are both frequently taught in high school math classes, yet one is a way to remember mathematical definitions (not a trick!) and the other is a random association for a limited procedure (a trick!). So what about if a student creates their own strategy or trick while learning math?

Join our hosts in trying to make sense of how and when remembering strategies are helpful and when they might be more harmful.
