I can do fairly complex calculations in my head and that is exactly the method I've used all my life. I'm glad to see it's been formalized.


Adults, and advanced children/teen can do complex calculations in their heads but we didn't start out doing complex calculations in our heads. Instead, we were taught the basic building blocks and then, only after understanding those memorization building blocks, were we able to branch out and learn how to do complex calculations.

Common core is idiotic because it sees what higher functioning students are able to do and mistakenly believes that every student can immediately leap to learning the complex calculations without teaching them the basics first.

ETA: I have no problem with using common core methods in schools but not until the students have a grasp of the basics. You can't build a house without a foundation so why would anyone think we can skip the foundations of math without any problems?

This IS the foundation. I have used this technique all my life.

And memorization comes after many repetitions. But the fundamental MATH is what is important.

And having this technique as a basic tool makes algebra a breeze later on.

Yep. I remember from high school that calculus was easier than trig which was easier than geometry. A lot of it was just learning shortcuts to what you already knew.

But if you don't take the other subjects first you'll be lost.

This math curriculum isn't Common Core. It's a math curriculum called "Everyday Math" and is undoubtedly the worst math curriculum to ever be perpetrated upon US children. It is designed to meet "Common Core" standards, but no school district is forced to used Everyday Math to meet those standards. They can use whatever curriculum they want.
