The Common Core makes simple math more complicated. Here’s why.
This math is frustrating to parents and to some students — with good reason. Elementary school math has become more complicated since the introduction of the Common Core state standards, which require that elementary school kids not just know how to subtract, multiply and divide, but understand what they’re doing and why.
Arithmetic has usually been taught like it’s a recipe: Take the raw ingredients (the numbers), follow a series of steps, and end up with a result (the answer). While an experienced baker knows why you cream butter and sugar before adding eggs, then add flour last, a beginner just following the steps is in the dark. They might know what to do, but they can’t explain why.
