Anyone think the math in elmentary school is simple, I think it is extremely hard for kids, it take me 40 year to understand.

The Five Strands of Mathematics Proficiency
(1) Conceptual understanding refers to the “integrated and functional grasp of mathematical ideas”, which “enables them [students] to learn new ideas by connecting those ideas to what they already know.” A few of the benefits of building conceptual understanding are that it supports retention, and prevents common errors.
(2) Procedural fluency is defined as the skill in carrying out procedures flexibly, accurately, efficiently, and appropriately.
(3) Strategic competence is the ability to formulate, represent, and solve mathematical problems.
(4) Adaptive reasoning is the capacity for logical thought, reflection, explanation, and justification.
(5) Productive disposition is the inclination to see mathematics as sensible, useful, and worthwhile, coupled with a belief in diligence and one’s own efficacy
Most kids can only achieve Procedural fluency, for Conceptual understanding is far beyond their ability, just ask yourself, why
1+ 2 = 3, or 分数乘法规制, Do you understand why?
My education goal is to achieve Conceptual understanding, not doing math by ritual, rote memory without understanding.

这就是美国老师的问题所在。1+2=3也能整篇论文。学生还是做不好。
