Ask, how to teach children addition and subtraction within 20? The first step: let the children learn to count skillfully. These requirements are:
1, can skillfully count down from "1".
2. Be able to count skillfully from a certain number in the middle. For example, the teacher said: count from 4; Count from 12.
3. Be able to count down from a certain number in the middle skillfully. Example: The teacher said: Count down from 4, and count down from 12.
Counting is the learning content of small classes, and our teacher thinks that every child should be able to count. However, we ignore that many children only start counting from "1". If you ask him to count from a number in the middle, they may not know how to count. Or children don't know how to get from 9- 10, 19-20, 29-.
The second step: let children master the relationship between numbers skillfully;
For example, what is in front of 5? What's behind? 8 What's ahead? What's behind? Counting forward from 5, counting backward, counting from
1 1 Count forward and count backward.
The third step is to let children master the relationship between numbers: for example, which is bigger, 7 or 8? 12 or 4, which is bigger?
The fourth step is to let the children learn to read the questions. Many children can read the questions, but they can't understand them. Children know the way of "+"and "-".
But I don't know how to read it. Let the children read it, prepare for the next calculation, and tell them: when you read "add", it is.
Countdown. When you read the minus sign, you count forward.
The fifth step is to teach children to know the unit and ten, so that children can skillfully say what the unit and ten in two digits are.
For example: 15, the unit is 5, and the decimal number is 1.
The sixth step is to teach children to calculate:
1, plus or minus hand index:
Addition, such as: 15+2= We tell children: Keep the big number 15 in mind and point out the small number 2 with your fingers (let children
Put your finger out), there is a "+"in the middle, that is, point your finger from the number after 15, and then follow 15.
It is 16, which means 16 and 17, so it is 15+2= 17.
Subtraction, such as: 15-2= We tell our children: Believe in big numbers 15, and point to small numbers 2 with your fingers (let children
Put your finger out), there is a "-"in the middle, which means counting down from the front of 15, and before 15 is 14.
The last two fingers are 13, so 15-2= 13.
Addition, for example: 15+2= We tell children that the sum of one digit and one digit is 5+2=7, and the sum of ten digits is.
1, then 15+2= 17.
Subtraction, such as: 15-2=, we tell children that the subtraction between one bit and one bit is 5-2=3, and the subtraction between ten bits and ten bits.
1-0= 1, then 15-2= 13.
How to teach 1 addition and subtraction in ten minutes?
Start with addition and subtraction within ten. It can be combined with objects that can be expressed by quantitative concepts in life. Such as apples, oranges, lychees, tomatoes, mangoes, etc. , can improve children's interest and let him know the important role of learning mathematics in life.
2. Consolidate the achievements
Parents should use all available time to ask questions to their children. As long as you have free time, you can ask questions and speak quickly, which will give your child a sense of urgency and exercise his habit of thinking quickly and improving efficiency. Parents can say 3+2, 5+4, 9-3, etc. As long as the child answers correctly, he should be praised, "Great", "Great" and "My child is really smart". The addition and subtraction within 10 should make him particularly skilled before entering 20 and before transitioning to 100. Not too fast, step by step, the best effect.
3. Consulting skills
Addition and subtraction within ten, once again, must make children extremely skilled. Achieve the effect of blurting out. Don't worry. It is necessary to tell children that addition and subtraction are complementary, especially within ten minutes, which helps children understand.
Addition and subtraction within 20 should be based on children's mastery of addition and subtraction within 10. Those within ten are very skilled, and those within twenty can master it quickly. At this stage of consultation, some written calculations are needed. Parents can find a horizontal book and randomly press 1+ 1, 1+2, 1+3 to ask their children questions ... 1+20, 2+6558 on a piece of paper with about ten pages. Up to 19+ 1, the advantage of this question is that any combination of numbers within 20 can be taken into account by children. So is subtraction.
/kloc-the same is true for exercises within 0/00.
4. Regular rewards and punishments
If you want to give your child a regular exercise, you can also give him 50 or 100 questions until the time. After the child finishes, grade him with a striking pen and store it, so that he can feel his little progress and improve his interest in practice. Give a reward for working overtime, and use a small punishment slowly. It depends on the study at that time.
What kind of boxing is easier to learn? Satisfied with the tangled answer, Bigfoot level 5, 20 1 1-07-04 Tai Chi is the most difficult ... I am embarrassed to say this. Learning boxing depends on your needs. If you want to fight in actual combat, I suggest Sanda, not paying attention to flowers, and directly aiming at fighting, which is more useful. If you perform ... I don't understand. Traditional boxing seems to perform well, but I'm not saying that traditional boxing is to show off. The level of a martial art depends on the individual's cultivation level. Follow-up: I downloaded the teaching video of Wing Chun Boxing before, and found it a bit difficult to practice after watching it. I don't know what is easy to learn. I can answer them in actual combat or performance: first of all, I have to understand that any boxing is difficult to practice, right? You think wing chun is difficult because you have studied it specially. If you persist, you won't have to ask questions here, but you are already an expert. Real boxing is not simple, even if it is street self-defense. I'm afraid opportunism won't do. You can consider Sanda, combined with equipment practice, such as nunchakus, and progress will be faster.

How to learn Korean is easier, easier to learn? Hello, I am now working as a Korean tutor in Beijing. The textbook used by students is the standard Korean of Peking University Publishing House. I once studied Korean in Beijing Foreign Studies University, and the textbook I used was New Standard Korean by FLTRP. In today's increasingly international society, driven by both economy and culture, many people are not satisfied with mastering only one language and begin to take multilingual learning as their advantage in the fierce competition. In the choice of multilingual learning, the upsurge of Korean learning is also heating up, which has become the first choice for most people. Through the study of Korean, students' advantages in employment and study abroad have become more and more obvious; In the process of language learning, the contact with Korean culture has also broadened and enhanced many students' horizons and ideas. Really feel that one more foreign language is one more world. So, for beginners, how to get started quickly and master Korean? Here, I would like to make some suggestions for your reference: 1. Mastering phonetic symbols and expanding vocabulary Korean characters are alphabetic characters, so mastering the pronunciation of Korean letters is a top priority for beginners. You can choose a special Korean voice tape and play it repeatedly to imitate pronunciation; Writing silently while imitating is very helpful to consolidate memory. Moreover, words are the cells of language, and some beginners seem to be at a loss in the face of a sea of words. In fact, most Korean words are Chinese characters, so you can remember them by corresponding them. As long as you use this method, you will feel that your power to remember words is really overwhelming. Second, pay attention to oral summary grammar Korean grammar points can be described as complex, and many beginners are shocked by the oncoming grammar knowledge. However, please remember that as a beginner, boring grammar and rigid rules are not your companions, but vivid spoken English and wonderful dialogue are your wealth. When you have fluent spoken English, you will find that it doesn't need hard work. Third, cultivate interest and inspire morale. Some friends who are beginners in Korean have low morale after a period of introduction. How to cultivate interest in learning at this time? You can choose a wonderful piece of an original Korean drama, such as vanilla, imitate it repeatedly, and then record it and compare it with the original sound. After a few days, you will find that you have not only improved your interest in learning, but also developed an authentic Korean accent and become an excellent performer. You may complain that Korean is not as ubiquitous as English, but don't forget the wonderful world of the Internet, because here you can download Korean support software, learn the basic knowledge of Korean, enjoy Korean music movies and listen to Korean radio and TV programs, so that you can enjoy the elegance of Korean and create a Korean environment without leaving home.
