Learning and thinking is actually a training class to teach children mathematical methods, so if children can master and analyze mathematical problem-solving methods, learning and thinking is not bad. If children do math by feeling and are not good at summing up the law of solving problems, then learning and thinking may not be suitable for children.

My child is studying, thinking and studying. It should be said that its content conforms to the teaching progress of primary school mathematics textbooks, and there will be no problems beyond children's cognitive ability. And although the essence is quite the same, the topic of learning and thinking is very different from that of mathematics textbooks, so it will not cause children to lose interest in textbooks.

My child is good at math, so it is hard to say whether studying and thinking will help his school. But I think it is very helpful for him to supplement his mathematical knowledge and enrich his mathematical problem-solving methods.

In particular, every learning and thinking about mathematics is to solve a kind of problems (mostly applied problems), and some interesting names will be taken. My children remember the names of every course about learning and thinking, and the way to tell every kind of problem like a story has always protected their interest in mathematics.

But then again, if children themselves are not interested in inductive problem-solving methods, they may find learning and thinking boring. So whether it is useful or not varies from person to person.
