Mathematics cultivates a person's systematic thinking. A person's systematic thinking is strong, and his overall ability to control mathematics will be strong, which has nothing to do with cleverness. Especially in the primary school stage, because primary school students' mathematics is the most basic, starting with knowing numbers, compared with other subjects, primary school mathematics as a whole is very simple and not too difficult. Is it too simple to measure children's intelligence with this? And not practical.
And in my opinion, academic performance can't measure a child's IQ. As long as a child can form good habits, or is gifted in which subject, the subject will be good, which only shows that he is good at doing this together, but not that he is smart. So parents must avoid this misunderstanding. If they want their children to develop in an all-round way, they must keep a balanced level in every subject.
And don't tell children that they are smart children as long as they learn math well. Children themselves will only like learning mathematics more, just to prove that they are smart. Parents should give correct guidance and don't give him such a wrong cognition. If they want to correct it later, it will become very difficult. After all, all learning is quantitative change, which leads to qualitative change. Wrong cognition will ruin a child's life.
Generally speaking, he is good at mathematics only because of his excellent logical thinking and systematicness. Don't impose this on cleverness. Moreover, his math scores will decline in the future, and children will have doubts about themselves. Labeling children too early is actually harmful to them. Therefore, parents must keep a cool head at this time.
