I grew up being taught ‘borrow and carry’ methods. They are really methods of ‘apply the algorithm and success’. Common Core can be a better way of getting an intuitive sense of the numbers and quantities.
Some examples are over the top, like the 32-20 in the article. But one of the common criticisms my parents and grandparents used to level at people my age (when I was a teenager) was that we couldn’t run a cash register—-we didn’t know how to make change.
Kids won’t start out adding and subtracting as quickly. The ramp-up to learning may be a little slower but they’ll come out with a more intuitive sense of numbers.
All of this is just my opinion. I studied Math and have a couple of young kids going through these methods in school now.
