Math teacher final review preparations: dry goods! Elementary geometry, all compulsory knowledge points
Elementary geometry is a compulsory knowledge point. Geometry questions are a common type of questions in math exams. Regardless of whether it is a flat or three-dimensional figure, it is almost a fragrant piece of the content of the mathematics exam proposition. When students start learning geometric figures, there must be geometric bodies on the test paper, so the mastery of geometric knowledge is necessary. Often parents come to students' classrooms and they will ask me if the math I have learned recently is too difficult. It is a bit daunting for parents to see the graphics in the children's exercise book as parents ...

20-year math teacher solemnly reminds: 3 kinds of elementary schools must be wrong in every test, must not be taken lightly. In elementary school, it is the key to lay a good foundation in mathematics and develop interest in mathematics. Mathematical thinking mode gradually emerged in the third grade. Many elementary school questions are confusing for many parents, and are the most common type of questions for children. In the last few exams, I found that the error rate of children on several types of questions is as high as 80%. It is normal for children to be careless, and their analytical ability cannot be foolproof. .

Parents of this set of sixth grade math test questions must be well received, practice their skills before the test, and worry less when they are at the beginning.
Parents of this set of grade six math test questions must be collected, practice their skills before the test, and worry less when they are young. However, for many parents and students, choosing the right math problem is a difficult task. Parents may not choose, and children will only choose the problems they will do. The small primary exam is the first major test before the children's exam, so it is necessary to practice more math problems. The difficulty setting of the math test paper is relatively fixed, so this is a more classic sixth grade. ..

This is also an important content for me to teach to my elite class children. I hope to help everyone! First, the division method. Third, the multiple ratio method. Seven, expansion, reduction method.

The 26 most prone to mistakes in elementary school mathematics! Don't go on wrong!
The 26 most prone to mistakes in elementary school mathematics! Primary school mathematics knowledge is the simplest part, but often the simplest is the easiest to make mistakes. I believe many parents must have this experience. Student performance is not bad, but it is easy to make mistakes, lose points for no reason, and correct mistakes When the child sees it, they know where they are wrong. I have summarized the 26 most error-prone knowledge points in elementary school mathematics. Parents can make targeted exercises based on the situation of students, and make up for missing ones!

The Problem of Proportion (3): Use a Math Problem to Learn the Three Properties of Proportion
Since the land area: ocean area = 29:71, then, the land area of the northern hemisphere: Earth surface area = (land area of the northern hemisphere: land area) × (land area: earth surface area) = (29: 100) × (3: 4) = 21.75 %. Since the land area of the northern hemisphere accounts for 21.75% of the earth's surface area, the ocean area of the northern hemisphere accounts for 50%-21.75% = 28.25% of the earth's surface area. The ocean area of the southern hemisphere accounts for 71%-28.25% = 42.75% of the earth's surface area. Ocean area: Ocean surface in the northern hemisphere ...

13 math problems and 13 points! One article is completely resolved, and no more mistakes
13 math problems and 13 points! What is the purpose of learning mathematics? I think this is also a long-standing question for many children and parents. In fact, mathematics subjects before the university were mainly for one purpose: to cultivate mathematical, image, and spatial logical thinking. These three kinds of thinking happen to be the most scarce in primary school children. Similarly, these problems can reflect another phenomenon: the child's ability to solve problems from multiple perspectives. The main reason for the difference is the difference in brain thinking ...

The answer to the "potential rules" of Chinese: learning Chinese for several years is worse than memorizing these 10 pictures?
The answer to the "potential rules" of Chinese language: It is better to study Chinese for several years than to memorize these 10 pictures. Take Chinese as a metaphor. Chinese is the most basic and most important of all subjects. Starting from the first grade of elementary school, graduating from high school, and even studying at university, how many people dare to say that they have fully grasped the essence of Chinese? Chinese practice questions are a bit different from other subjects. Many of the contents have the same rules and rules for doing problems. Students ...
