In the question to the left, pay particular attention to the bottom. Common Core stresses learning how things work, over getting a right answer.
Children learn by the first concept they are given. For example a young child can learn two languages easier than a crusty adult. But teach them wrong, they keep it for life. Not saying “ain’t after hearing it all your life.” is next to impossible. So the way these children are taught, is their core.
Whereas this is interesting to look at, one must question how this child taught in such a way, will someday on his SAT’s be asked to add 10,909 plus 39,777….
How is he going to draw all those little circles?
