Common Core

You just take it for granted because that's how you learned it. Not all binary operations are commutative.

I'd love to see the logic behind this

But knowledge of commutative property does need to be shown.

I expect the teacher even reminded kids to write answers in full just as they were taught. Mine always did. If he didn't, he's a shitty teacher, but that's not a problem of common core.

Common core math has merit behind the idea, it employs techniques that people use who do "fast math" in their heads (and appear to be geniuses).

But it should not be forced on everyone. Teachers have no choice thought because they can only teach one class at a time, and there 25 or 30 kids in a class.

Just for the record, I do not approve of the methods of common core.

this, it's a good concept but the way they're putting it into practice leaves much to be desired
