Children will encounter temporary obstacles in learning mathematics, be embarrassed and doubt themselves. But if we don't even trust children as parents, then the power of children to finally stand up will disappear. Only when parents always trust our children will there be a blue sky in their hearts and they will be able to stand up. Mathematics is consistent, primary school mathematics is the foundation of junior high school mathematics, and the foundation is not solid. Some people think that primary school and junior high school are two different stages, and there is almost no connection. In fact, it doesn't understand the mathematical system. For example! This is the basic knowledge of primary school mathematics. Speed × time = distance, distance/speed = time, distance/time = speed. You must master and flexibly use the relationship between them. Junior high school students learn the number of one-dimensional linear equations and one-dimensional quadratic equations, as well as binary linear equations, binary functions and even inverse functions. Use the three basic relationships of speed, time and distance to list equations or functions. If primary schools don't learn flexible application, junior high schools will definitely be affected.
Primary school mathematics is mainly mathematical operation. Compared with primary school mathematics, one of the biggest characteristics of junior high school mathematics is to explain the background, that is, to write clearly the process and thinking of the answer, and to pay attention to cultivating students' strict logical thinking and reasoning ability. If students' thinking has been stuck in the operation of primary school mathematics, it is difficult to adapt to the complex reasoning and proof deformation of junior high school mathematics, and their grades will inevitably decline. A student must have a particularly classic math sample book. Some people think that exams are not a problem. What's the use? Classic examples don't ask you to guess. Classic examples are the embodiment of knowledge points. There are hundreds of knowledge points in the twenty-ninth chapter of junior high school mathematics. If each knowledge point has a corresponding example, the review efficiency is too high. Avoid just reviewing reading or going to sea tactics, but pay attention to giving only one example for each knowledge point. Mathematical operation ability is the basis of mathematical learning. It is almost impossible to learn mathematics well without good computing ability. I learned mathematics addition, subtraction, multiplication and division in primary school, which is the basis of junior high school mathematics learning.
The study of junior high school mathematics begins with mathematical operation, real number operation, one-dimensional linear equation operation, two-dimensional linear equation operation, one-dimensional quadratic equation operation, fractional equation operation, inequality and inequality group operation. Equation is the core of mathematical operation in junior high school. The most difficult function of junior high school algebra is essentially a linear equation and a quadratic equation. Function learning is also inseparable from operation. As long as the calculation ability passes, the math algebra part of junior high school is basically no problem. The most difficult thing in mathematics learning is the way of solving problems. For some simple questions, you can answer them in the normal way, but for some difficult questions, you need to master some mathematical ideas, equation ideas, classified discussion ideas, number combination ideas, overall ideas, hypothesis ideas and so on. Every thought and method has its specific function. In daily study, only by mastering the core of these thoughts and their usage can we use them correctly and deal with them flexibly in the exam.
