Yes.
Times tables for instance. Good thing!
Looking at some of my cousins Common Core math sheets it is clear this new system is based on pure retardation. They aren't even taught how to do proper math problems.
The way they want it done teaches nothing except how not to solve a math problem in an efficient and logical manner. Not to mention they can put down the wrong answer and still get it right somehow.
We ne3ed to go back to actual teaching instead of this fantasy common core BS.
