I t just adds unnecessary steps to achieve the same objective. Like if I want us to walk across the street and watch kids play ball, first we have to walk through 3 surrounding neighbors yards for no apparent reason
Until I first started working with my 10 year old grandson, I never understood how my grandfather, who had only a second grade education, always had the answer to any arithmetic problem, regardless of the complexity before I did. He never used a pencil and paper.
It also explained how my youngest son, now 45, was taught in kindergarten, everything I was taught in elementary school. He was taught by an art teacher. Since his other elementary school teachers and I had very little experience with the kindergarten methods, he had a terrible time in the rest of elementary school. Since my 10 year old grandson's teacher's understand the methodology, he is working problems in the fifth grade that I didn't see in high school.
As I stated earlier, we need bite the bullet and start learning with our children. Everyone be surprised at the problem solving tools that he/she will develop.
