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 followed ladder mathematics into the world of addition and subtraction. 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. The so-called ten-point method, such as 8 7=, is 8 7=8 2 5= 15, 16-9 = 16-3 = 7. This algorithm requires children to be familiar with internal addition and subtraction and the composition of 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) = 5014 = 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 2714 = 27104 = 37 4 = 41,and the thinking is correct, but my method is 2714 = 201074 = 30/kloc-0. Borrowing and subtracting two digits is the only time I taught it first, 54-28 =, my idea is 54-28, using 50-20 first equals 30, 4-8 is not enough to subtract, from 30 borrowing 10, then 30 becomes 20, and then using14-8 = 6,206. 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. 4. Be your child's best friend. In practice, we can also sum up some experiences and treat them according to specific conditions. The improvement of children's computing ability is based on oral calculation. The addition and subtraction within 10 is the basis of carry addition and subtraction, so the addition and subtraction within 10 must make children very skilled. No matter parents or teachers, they should teach and coach from the easy to the difficult. In teaching, let children learn tools (counting sticks, toys, various graphics) and so on, so that children can understand the composition and decomposition of numbers in the process of hands-on operation, and then teach addition and subtraction, because the composition and decomposition of numbers are the basis of addition and subtraction teaching within 10, and it is much easier to do oral calculation of addition and subtraction after mastering the composition of numbers. The purpose of linking addition and subtraction with the composition of numbers is to let children really understand the operation of addition and subtraction. Taking the composition and decomposition of the number "5" as an example, "5" can be divided into "2" and "3", and "2" and "3" make up "5". Addition means to combine the two parts and work out a * * *, how much. " "2" and "3" make up "5", which means that "2" and "3" are combined, that is, 2 3 = 5. Subtraction is to remove a part from the total and find another part. 5 can be divided into 2 and 3, that is, 2 is removed from the total number of 5 to leave another part 3, and 3 is removed to leave another part 2. That is, the teaching of addition and subtraction within 5-2=3 and 5-3=2. 10 can be carried out from the following four aspects: (1), children manually operate learning tools and get the composition of numbers through learning tools. (2) Master the composition of numbers. You can say the composition of numbers while calculating; You can make the composition of numbers into cards for training. Look at all kinds of cards and let the children say, preparing for addition and subtraction. (3) Formula calculation. Based on the composition of trees, the calculation result is much simpler. (4) Training of addition and subtraction in oral calculation. On the basis of children's understanding of arithmetic, carry out various oral arithmetic exercises. Make the composition of numbers into cards for practice. Taking 5 as an example, it can be divided into 2 and 3. Showing cards can not only let children tell the composition and decomposition of numbers, but also tell two addition formulas and two addition formulas by looking at cards. In addition, you can make a dictation card for practice, such as: 2 3 = 5, you can write out the results first, let the children read the formula completely, and then remove the results for the children to read; Finally, look at the formula and tell the result directly without repeating the topic. This step by step can take care of children with poor language skills and improve their language skills. In addition to practicing with the above methods, we should also pay attention to children's listening and counting. Listening and counting can cultivate children's attention, exercise their listening ability and improve their thinking and reaction ability. This is also the purpose that we now let our children copy the calculation questions to the blackboard every day in the garden. Addition and subtraction within 10 is the basis of learning addition and subtraction within 20, so we must educate and urge children to master it skillfully. According to the composition of speaking numbers, reading dictation cards, writing dictation questions, reading dictation questions and listening to arithmetic, gradually improve the speed of dictation. As long as you persist and persevere every day, you will certainly achieve good results. When teaching children the addition and subtraction within 10, you can often make up some short stories for children to participate in, and before you know it, children will learn the operation. And every time children show great interest in this kind of short story, it is very easy to learn addition and subtraction. For example, learning the addition and subtraction of 8, I made up such a short story, in which I often interacted with children, asked each other questions, and even asked them to make up stories: the little monkey wanted to buy 8 apples for his grandmother. When he came to the market, he saw that the red apple was attractive and the green apple was good, so he bought some of the two apples. Five red apples and several green apples? ) The little monkey walked happily to grandma's house with a box containing eight apples. On the way, I bumped into a pig and knocked off an apple. They don't know. How many apples are left at this time? ) The pig is a good friend of the little monkey. It's good to see a little monkey. When the pig said he was thirsty, the little monkey gave him an apple to quench his thirst. How many apples are left at this time? Seeing the pig eating the apple with relish, the little monkey wanted to eat it, so he took an apple and ate it. How many apples are left at this time? Suddenly, there was a lion's roar behind him: "Ho-"No, the lion saw the little monkey, run! The little monkey ran hard with the box and the apples in the box fell out. Finally, I ran to grandma's house, but the lion didn't catch up. The little monkey finally breathed a sigh of relief. The little monkey gave the apple to grandma, but it looked into the box and said, "Hey? Why are there only two apples left? "Grandma smiled after listening to what happened on the road told by the little monkey. Grandma said to the little monkey, "You are the best gift!" " "In this way, the story is over. In the process of speaking, I also ask my children to count how many apples there are from time to time, and the story of meeting the lion later is also made up by the children themselves. The whole process is very easy, which not only allows children to develop their thinking, but also achieves the purpose of learning.
