The picture above is from my third grade daughter's math book. This is the only page that explains that method for subtraction. There are, for the record, four ways to subtract that my third grader must learn.
This is the only page explaining that method. This is the only example. The very next page goes to arrays. The page after that goes to multiplication. This is it.
The traditional method of subtracting, borrowing and carrying numbers, is derisively called the "Granny Method." The new method makes no freaking sense to either my third grader or my wife.
We send our child to a Christian private school. We thought our child could escape this madness. But standardized tests, the SAT, and the ACT are all moving over to Common Core. So our child has to learn this insanity. But we cannot help her. The book offers only one example.
This is maddening and angering and frustrating. This is why so many parents are so upset. They cannot help their children. The math makes no sense and seems to offer no practical purpose other than it is new. The teachers privately concede the uselessness of it.
But major corporations and government entities insist that it be done. Parents and children feel helpless. My wife wants to murder someone over it.
This is why Jeb Bush will not be President. It is also going to end very, very badly for many other politicians. The only champions of common core I know are paid to like it and most of them have no kids. These people want worker bees in their cogs. They want automatons. They do not want productive, independent citizens.
