Let’s look at what kind of requirements junior high school math teachers give to children in sixth grade.

We had an article before that said parents who are entering junior high school are the most confused group of parents. It\’s not so much confusion or anxiety. Every year, parents of sixth graders ask, how to review sixth grade math? Regarding this issue, let’s listen to some requirements put forward by this junior high school mathematics teacher for sixth-grade children, for your reference only. (The following materials are collected from the Internet) The teacher said, if you meet my requirements, you will definitely be able to learn junior high school mathematics very well. Three core things to review. The first point: Be sure to review calculations carefully. It is not an exaggeration to describe the proportion of calculation in primary school mathematics as half of the country. I believe that many parents will give their children some oral arithmetic problems to do every day since they are in first or second grade to enhance their children\’s number sense. However, the calculation level of many sixth-grade children in primary school is far from meeting the requirements in junior high school. How to do it? Note two points. The first point is that the distributive law of multiplication has been learned since the third grade of elementary school. Many children really cannot understand it. When removing and adding parentheses, do you change the sign or keep it the same? Often confused, sometimes based on feeling. This situation will become a big problem in junior high school. Because the calculation of rational numbers in the first grade of junior high school must involve a large number of bracket-removing operations. If you don’t understand this, the chance of making an error is quite high. At that time, it will seriously damage the child\’s self-confidence. So if you didn\’t learn it well in elementary school, you should hurry up and get familiar with it. The more familiar you are, the better. It\’s better to be extremely familiar and proficient. The second point is to pass the mixed operations of addition, subtraction, multiplication and division of fractions, decimals and percentages. You must be very familiar with the techniques involved in fractional operations. It directly affects your computing ability in junior high school. Practice this thing well. The second thing to review is the content of geometry. Relatively speaking, geometry in primary school is relatively shallow. Most of the things are not of much use in junior high school, but area is very useful in junior high school. The area of ​​all shapes in primary school needs everyone to be able to use it flexibly. The third one is very important: application questions. A few core points, the first is that all types of word problems must be understood from the bottom level, not just a simple set of formulas. Let me give you an example. When learning engineering problems in primary schools, many children just use formulas or unit 1. This is far from enough. In junior high school, he will break this engineering problem into several sections. In this section A and B will work on it, in this section B and C will work on it, and in this section A, B and C will work together. Therefore, we must emphasize the need to have a basic understanding of the formula. No matter how it is produced, if I can understand it, I can list the formula, and I can solve the problem. The second requirement is that in this part of the application questions, children must be allowed to practice multiple solutions to one question. Some people say this is a waste of time, but it is not. It can effectively improve children\’s sharp reactions, and their mathematical thinking will definitely be improved. The advantage of having multiple solutions to one problem is that it breaks the shackles of children\’s thinking. They can use different knowledge to solve the same problem from different angles and ultimately reach the same goal. Doing one question is equivalent to doing multiple questions for others, and such children also have strong advantages in summarizing. They have a pair of eyes that are good at discovery. The older the junior high school students are, the more they think about their children.The higher the dimensionality requirements. If nothing else, isn’t it the same when we do things in life? For example, a company cannot completely rely on one person to operate (that is, what people call the main artery). If he is not there, it will not be able to operate normally. Then think about how terrible this is? If for some reason he can\’t come to work for a period of time, wouldn\’t the company be helpless? Therefore, there must be someone who can replace him at any time. Even if it is slightly worse, he must be able to maintain normal operations. Another example is some car manufacturers. When choosing tire accessories, they usually choose several tire factories to supply their products. Some people say that the factory is trying to save money. Maybe this is one of the reasons. In fact, there are other reasons. For example, if there is only one supplier and the supply cannot come, isn’t the joke too big? Furthermore, if there is only one supplier, and if a certain batch of products has quality problems, isn’t the car manufacturer doomed? You can focus on one company, but you can\’t make other preparations. This is why every local government can activate emergency plans as soon as possible when a major event occurs. Isn\’t this just extra preparation? If you are not prepared at ordinary times, why not be in a hurry? The third point is, what kind of child is really good at thinking and has a solid foundation? You can derive it backwards, learn it first when you don’t know how, and make sure you can teach others when you know it. This is also the essence of Feynman\’s learning method. When you can teach others what you have learned and make the other person understand and understand it, then you must have mastered this knowledge. Give roses to others, and the fragrance will linger in your hands. You can ask your children to give more lectures to their classmates, or to teach application problems to their parents. If you can explain it clearly, your child will be a real master of thinking. If you have grasped these three points, you can do a very cool thing next and learn the content of junior high school in advance.
