How to cultivate mathematical thinking? Play, yes!

I don't know if you and your children have such an experience. Next to the bus stop and the street next to the scenic spot, a fortune teller gives you several pieces of paper with many surnames on it and asks you which ones contain your surnames. After you say it, he can guess your last names. Does the child feel particularly magical? Similarly, a fortune teller can guess your zodiac sign, age and birthday. ...

In fact, fortune tellers only use mathematical methods. If you and your children master such mathematical thinking, you and your children can also design such games and become fortune tellers. How to do it specifically? Sun Luhong's book "Math taught by Dad" is introduced in detail.

Sun Luhong graduated from the Department of Mathematics of Beijing Normal University, and once worked as a middle school math teacher, calling himself a brain engineer. He offers various online courses to teach children and parents how to take care of their children. Courses and books will combine the psychological and cognitive changes in the process of children's growth, and most of them will adopt a way that suits children's reality and exercise their thinking from games.

Sun Luhong once published "Mathematics taught by Mom", in which mom combined with daily chores to stimulate his interest in learning mathematics. And "Mathematics taught by Dad" means that Dad pays more attention to let children explore and try to find their own laws, so as to exercise his thinking and cultivate his attitude and methods.

Personally, I don't like to distinguish the roles of father and mother too much, but whether it is father or mother, there are some things that parents should teach their children, and they need special attention.

First of all, the number games in the book are well worth playing. The second part is "the story between numbers", guessing numbers and ages can help children find their own rules and then solve problems by themselves. 15 win game, 34 win game and "calculate" game in the seventh TIC-tac-toe game can strengthen the flexibility of the brain and are quite interesting. In the eighth part, "Talking about the great wisdom in heaven and earth", you can learn how to guess the zodiac and surname, which is mentioned at the beginning of the article. Being a fortune teller is really interesting! In fact, all the games in the book are worth a try.

Second, don't ignore children's problems, chat with children more, talk about children's curious questions, don't rush to give children answers, think positively, and guide children to think positively. When appropriate, you can pretend to be deaf and dumb and pretend not to know. Don't just care about life and study.

Third, allow children to slow down and give them enough time to concentrate on one thing and be fascinated by one thing. Let children understand things from intuitive life, and when they learn the corresponding abstract mathematical terms, they will be easier to understand and more profound.

Fourth, encourage children to use pens, draw questions and write ideas. Draw more clearly, open your mind more easily, and write more carefully.

Fifth, don't let children brush the questions. Especially for primary school students, it is really not advisable to brush the questions, which will easily ruin their interest in mathematics and form a mindset.

Besides, I'm not satisfied with this book. For example:

First, I think the author overemphasizes the difference between father and mother, which is repeated from time to time. My mother gave me interest in mathematics, and my father complied with my understanding of the law. Mother gives care to life, gives a sense of security and interest in learning, while father, as a builder of self-confidence, gives a way of thinking, cultivates logic and shapes brave, firm and persistent characters.

The author's father may give it to many other people's mothers. In many families, the interest may be given by the father. In addition, when writing about the mathematical thinking and learning of boys and girls, the author will feel that there are differences between them, but I also feel that there is no such difference. Although the development speed of boys and girls is different, there may be differences in a certain period, but I always feel that the differences are between individuals, not between sexes.

Second, there are mistakes in the book. The question on page 143: "Think about two numbers in 1~ 10; Add two numbers; Multiply by10; Add the larger of the two numbers; Subtract the smaller of the two numbers. " He later said it must be three digits. You don't say! As long as the sum of these two numbers is less than 10, it is a double digit! There is such an obvious mistake in a math problem? The author himself has always stressed that mathematics should be rigorous. Is it so rigorous?

Third, the content is slightly repetitive. Although I understand the author's painstaking repetition of important things to deepen his impression. But I still feel that some words have been repeated too many times.

In the ninth part, "Abstract thinking is bred from guessing games", the guessing of numbers, the inversion of three numbers and the guessing of age are all mentioned seriously in the second part, "Stories between numbers". Does it mean that the readers of this book didn't read the book so carefully and turned it over before they understood it, so they read the ninth book and then read the author's slow analysis with relish?

Of course, these things I don't like are not very important, and the flaws are not hidden. This book is well worth reading.

So, how to learn math? How to cultivate mathematical thinking?

Play! Yes, just playing. Combined with point 2345 in the first part, play the first game, play all the games in the book, and play the games designed by you and your children inspired by life. Play, yes!
