Seventh grade math enters the mid-term review stage, and many students like to brush up on the problems, but if the basic knowledge is not solid, we must first sort out the knowledge points.
Every time after the exam, when the exam paper is sent down, there will always be students who say that they have lost a lot of points because of carelessness, and if they can be careful, they will definitely be able to get higher scores. This problem is widespread, but we need to analyze whether it is "real carelessness" or "false carelessness", because many times it is not because of carelessness that the result is wrong, but because the understanding of the knowledge points is not deep enough.
Compared with elementary school, the concepts, theorems, formulas, etc. in seventh-grade mathematics have increased a lot, and if they are not paid attention to, it is easy to remember, confuse and understand them thoroughly. For example, intersection lines and parallel lines, real numbers, the concept is more, but many students do not pay enough attention to the concept or the understanding of the concept is only at a shallow level, but when we do the problem, it is precisely the deep understanding of the concept to do the right question.
Today, I will focus on the second book of seventh grade mathematics, mid-term review, and share the test point combing. If you don't have a solid grasp of this part of the knowledge, I hope my sharing will be helpful to your learning.
