When we improve our math scores, we should grasp the foundation.

The previous multiple-choice questions and fill-in-the-blank questions need more training, especially the questions about several situations in the fill-in-the-blank questions. We should answer the questions according to the questions. The last one in the math fill-in-the-blank problem is to find the law. In the process of solving the problem, it is best to list all the changes on the draft paper, so it is easy to find. In addition, it is not difficult to find the rules in the senior high school entrance examination. It is best to remember some common rules of practice and apply them online if necessary.

Then there is the problem of solving the equation. Pay attention to writing the solution first. If it is a modal equation, we must check the root. Remember trigonometric function values when doing calculation problems.

Then, pay attention to drawing according to the requirements of the topic, and use black strokes after drawing, otherwise the computer will not scan it.

The big questions and application questions behind are the basic questions of normal training and will not be difficult. If you really can't do it, do as much as you can, and sometimes you will get points if you calculate some other quantities.

The most important thing is the last question. Generally speaking, the first question is very simple, and these points must be scored. Then the second problem may be to find the analytical formula of a straight line or the coordinates of the points that make up a right triangle. Similarly, how much can be done? The third question is, if time is too late, I suggest giving up and using time to check the previous basic questions. If the basic questions are all right, there is still time to think. Pay attention to the overall consideration, we are

In the third grade, after the establishment of the plane rectangular coordinate system, the learning of functions can not be separated from images. Often with the help of images, the problem can be clearly explained, and it is easier to find the key to the problem, thus solving the problem. In the future mathematics study, we should pay attention to the thinking training of "combination of numbers and shapes" Any problem, as long as it is a little close to the "shape", should draw a sketch to analyze according to the meaning of the problem. This is not only intuitive, but also comprehensive, easy to find the breakthrough point, which is of great benefit to solving problems.

Thank you. I hope it can be adopted.
