Reference articles may be helpful to your question. A few months ago, I was also a confused mother. How to teach my children math has become a headache for me. I always thought this was a teacher's business. Children can learn from teachers in kindergarten, but this child is very sensitive to mathematics. It seems that she can't wait for the teacher to teach her. After four years old, she entered the world of addition and subtraction with ladder mathematics. The more you don't care, the more you can feel the progress of your child. When the little guy learned addition and subtraction within 20 in September, I began to worry about how to guide my children to learn math. I don't know. I'm far behind the children in preparation. It is often found that children already know, and they begin to guide children to correct their algorithms in the fastest and simplest way. That's all right, at least children learn it on the basis of understanding, and there is no pre-school indoctrination. I have accumulated some experience along the way. First of all, to learn the basics of addition and subtraction, you must learn the number of 1- 100, the reciprocal of 100- 1, and the number of points within at least 20. These things were all done by blossoming children when they were four years old, especially the countdown, which surprised me because I had never taught her. So I often say that this child is very sensitive to numbers. Children who add less than 10 are very smooth, but children who subtract must see the real thing at the beginning to work it out, especially 10-9. We look easy, but the children find it difficult to calculate it. At first, when children tried to subtract big numbers from such big numbers, they always made mistakes. I just ordered the children to say, "10-9=, which is actually 10. In short, children within ten will pass the subtraction. I thought Duoduo only went to class this year, and I thought that this was enough. I don't want to accidentally find out that the little guy can already carry it. Although I knew I had calculated it in my mind, it still surprised me. So I began to look for ways to learn how to carry it with me. I found it in the word book that Duo Duo bought. The popular carry addition algorithm in 2 1 century is the complement ten method. Later, I asked the parents of preschool children and it was confirmed. For example, 8+7=, which means 8+7=8+2+5= 15, 16-9 = 16-3 = 7. This algorithm requires children to master internal addition and subtraction. 10. At first, I thought it was not easy for children to learn. I used diced mushrooms to make them feel familiar. A few times, I forgot. The fact is, when I did the problem later, the child clearly said the idea and used the method of ten plus one, only to find that the child actually understood it. When it comes to the carry addition of any two digits plus one digit, children still use the ten-point method, but depending on the type of questions, sometimes the front ones are put together, and sometimes the back ones are put together. I find it easy to make mistakes at this time. Like this, 58+6=, and 23+9=, fortunately, at this time, the little guy has been very skilled in addition and subtraction within 20, so after thinking, I put forward this algorithm: 58+6=50+(8+6)=50+ 14=64. Children accept it easily. Once again, I met the borrowing subtraction method. I told my children the concept of borrowing for the first time, because it only involves two digits MINUS one digit, so it is not difficult to understand. With the mathematical training of new thinking, it soon involves the addition and subtraction of two digits. It is easy to add and subtract integers, but neither number is an integer, and blossoming begins to make mistakes. I found that it is actually the concept that children don't have numbers, so we put them together to do the problem. Soon the children understood the relationship between numbers, and I also found the benefits of verbal calculation. When I speak, I read 24, and when I read 2, it means 20. This is much better than studying. And I have always disapproved of teaching children to count vertically when they are too young. Children who understand are better. Children who don't understand just do mechanical addition and subtraction within 20. Even if they can do it, they don't understand the relationship between the concepts of number and quantity. Moreover, learning oral arithmetic will only make it easier to learn vertical arithmetic, so I won't teach her vertical arithmetic, and leave it to the kindergarten teacher. The most difficult thing is the addition of two digits and the subtraction of abdication. I've been thinking about what to tell the children. I have been following my child since I started to learn addition and subtraction, and she will do whatever I teach her. At the end of this period, I took the initiative to think first, but when I figured out how to teach, the little guy came to me unconsciously. /kloc-one day in February, I wrote 27+ 14= when I was on a whim to teach my child to do addition. The child immediately stopped me and said, "Mom, you don't have to teach me, I can do the math. The child thought for a moment and blurted out, "4 1". I was surprised and asked, "How did you work it out? "Children's algorithm is 27+14 = 27+10+4 = 37+4 = 41,and the idea is right, but my method is 27+14 = 20+/kloc-0+7. Subtracting two digits by subtraction is the only time I taught it first, 54-28 =, my idea is 54-28, using 50-20 first equals 30, and 4-8 is not enough to subtract. Borrow from 30 10, then 30 becomes 20, and then use14-8 = 6,20. I know the children themselves are quietly digesting it. A few days later, when I asked again, the child had worked out the correct answer before I spoke. The addition and subtraction of blossoming flowers are all done in the state of oral calculation. Children are very interested in numbers and sensitive, so they make rapid progress, which even surprises me. In the whole process, I think the most important thing is to cultivate children's concept of number. This step of math and new thinking math training is very good, saving me a lot of time. In addition, the placement of mushrooms makes the concept of numbers clearer and easier for children to understand. Because my teaching process is mostly after blossoming can solve the problem by itself, the time for children to accept it is very short. I think it is also important for children to experience it themselves. Even if she can work it out in the most stupid way, it shows that she understands this numerical relationship. What we can do is to make it easier for children to understand and calculate. Interest is the best teacher for children! 1, first of all, we should cultivate children's interest and let them learn actively. Passive learning is boring and can only make children feel disgusted with learning. 2, always remember to praise children, praise is a stimulant to stimulate interest, learn to discover the advantages of children 3, have patience and confidence, and share the gains and losses in learning with children.
