023. Rules and Language that Expire [Part 1]

Today, we’re examining what happens when rules that students once learned in math class are no longer true, or in other words, they expire. Now, I know what you might be thinking, “If it’s a rule, how could it ever not be true? That seems like a contradiction.” And that’s a fair point. Let’s take a look at some examples and talk about it!

In this episode, we take a closer look at the kinds of shortcuts, tips, and language we use with the best of intentions (especially in early grades) that can cause confusion down the line. What starts as helpful guidance can quietly set up misconceptions that are tough to unlearn.

We’ll talk about what it means to “attend to precision” in how we talk about math and how to help students build understanding that sticks.
