Mathematical thinking is a typed composition for the fourth grade.
Others think Dongdong is born with a talent for mathematics, but I know that when he was a child, I taught him to count from 1 to 100, and he was worse than other children of the same age. It is an early game, which developed the "mathematical muscles" in Dong Dong's mind.

I always thought that Dong Dong's good math skills came from playing games when he was young, and I'm glad that we noticed his preference for liberal arts when he was very young, and helped him make up his math in time through games, so that Dong Dong's arts and sciences could develop in an all-round way and his academic performance could be guaranteed to be excellent all the time.

I began to teach him arithmetic when he was very young. I used to teach hard, but it didn't work. Counting from 1 to 100 is still wrong for many days. It is common to count to 30 and then jump to 50. At that time, I was very worried: teaching him such a simple number had no concept. How can he learn such complicated mathematical calculations after school? I don't think he is suitable for math. He lacks math muscles in his head, but his talent in language has been shown very early, which is much better than other children.

In order to keep up with the progress of math class after school, there is no way for a stupid bird to fly first, so I began to work hard on his math study.

I remember when Dongdong was three or four years old, I began to help him work hard on mathematics, starting with small things in daily life. After washing the apples bought at home, start putting them in the fruit bowl. I will let Dongdong and I count the apples on the plate one by one until we know how many there are, then take out a few and count how many are left. In this way, Dongdong began to understand numbers.

I also mentioned addition and subtraction in passing, whether he understands it or not, I believe he will understand it gradually. Before eating, rice bowls and chopsticks are placed on the table. I'll ask him to count several bowls and chopsticks, and then take another bowl. I lost no time in asking him, adding another bowl. How many bowls are there now?

In this way, after going down many times, I finally got the concept of numbers. He even asked me, "Mom, why did we take three more bowls?" So I told him that after cooking soup today, everyone needs a bowl of soup. At this time, I was already very happy, and the math muscles in Dongdong were clearly found soon.

When Dongdong was 4 years old, we started playing poker, mainly "Catch Bigger". That is, several people take turns to draw cards. Whoever gets enough 2 1 points first, or whoever gets more points wins, or whoever gets less points or gets caught loses. Sometimes our family plays together, and sometimes he plays with his cousins. This "grasping the big point" is an addition exercise, only in the form of playing poker, and it also talks about winning or losing, and there is a reward for winning. So Dongdong enjoys it, often holding poker by himself, pulling me and his father to play "catch bigger" with him, but I don't know that this is exactly what I want.

After playing catch bigger for a while, we played catch 30 again. This game was invented by three children in my sister's family, and I played with them in winter and winter. The general game is that two children draw cards in order from the beginning and take turns to count. You can do one at a time, or even two at a time. Whoever gets 30 first wins. This is much more difficult than "grasping the bigger point". It is no longer the calculation by luck and addition, but the logical operation and numerical analysis. Because you should not only consider yourself, but also guess what your opponent's psychology is, and then consider how to grab the most critical figures.

Dongdong and his little cousin are both competitive children, so every time they play "Grab 30", they are quick-talking, quick-thinking and quick-calculating games. This makes both children develop the habit of quick and accurate mental calculation, so that they can answer questions quickly and accurately in future math exams, which will benefit them for life.

By the time I was about to go to primary school, Dongdong was already interested in mathematics. We often go to bookstores to buy math books, especially some interesting math books, which we read with relish in winter and winter. His father and I often give him some interesting math problems with books, and he has little strength to do them.

I still remember doing the interesting question "Farmers Crossing the River": "A farmer came to the river with a dog, a rabbit and a cabbage. He wants to cross the river with these three things. But there is only one boat on the shore, and the farmer can only take one of them on board at a time. How can he take them all across the river? " Together, we found a little doll as a farmer, a toy dog and a rabbit, wrote the word "dish" on paper, made a small bridge with a ruler, and began to do this problem. Dongdong knelt on the ground, swayed from side to side wholeheartedly, and soon shouted, "That's right! Do it well! " It turned out that he really figured out a way for farmers to cross the river. Look at him happy. He is happier than what he bought him.

Dong Dong began to be interested in this interesting math problem before he went to primary school, and the more difficult the problem, the more excited he was, and the more excited he was when he finished it.

I remember a story about a cook who beat eggs. Give the chef 15 eggs, let him beat the eggs into four bowls first, and ask how to beat the eggs, so as to ensure that the customers can fry as much as they want. At that time, I put 15 Weiqi pieces together in winter and winter, and then tried to spell a few pieces, and I also finished the problem quickly.

Later, he did this interesting math problem faster and faster, and slowly he didn't have to put on a physical demonstration, so he could work it out quickly by using his head. Later, Dongdong didn't need adults to give him questions, so he often picked up a book and solved it himself.
