Graphics are the lifeline of elementary mathematics, and whether it can support thinking activities is the key to learn elementary mathematics well. Whether it is geometry or algebra, drawing should be the first to get the problem. Sometimes some simple questions will come out directly as long as you draw a good picture. When you encounter a problem, you need to draw a picture, which can clearly present the known conditions. And draw a picture at least once when solving the problem, so that it looks clear and the thinking is smooth when doing the problem.

First of all, you should have the consciousness of drawing in your mind, form a conditioned reflex, and draw pictures first when you have a math problem. Moreover, we should have a useful sense of the picture. Drawing a picture without using it is equivalent to not drawing it.

With the consciousness of drawing and using pictures, you must have the skills of drawing. Some people say that painting is not easy. Who can't draw when studying math? Don't underestimate this. Many students don't have good drawing habits and can't use drawing tools. Neither compass nor ruler can be used, and drawing is ugly. We don't ask everyone to make the picture beautiful, but to be clear, clean and accurate, so that it will be helpful to do the problem. Correcting some bad habits of my painting can improve my painting ability.

What senior high school students need most is the ability to read pictures. Is whether more useful information can be extracted according to the given graph; And vice versa, can you draw an accurate graph according to the known conditions?

Now there will be math experiment questions in the college entrance examination, which is the product of the new curriculum standard, just to test students' comprehensive ability. Although the problem is new, as long as you analyze it carefully, you will find that all the knowledge used in solving the problem has been learned. The college entrance examination questions are very rigorous, and it is impossible to exceed the outline.

2. Summary after the exam

Teachers and parents always pay attention to the gap between students' performance and the last exam after the exam. Students who fail in the exam will always find various reasons, whether it is to comfort themselves or to comfort teachers and parents. Parents should not be too nervous after seeing their children's grades decline. As long as students develop good test habits, don't worry about their grades.

Students should summarize the following three questions after the exam:

First, what are the advantages of this exam? This is a process of self-affirmation. Too many people ask students to summarize the reasons for losing points, but they ignore that students get a lot of points in addition to losing points. Students should objectively analyze the scores, which are easily obtained by their solid knowledge and problem-solving skills; What are some points that I have a general impression in my mind and a little luck? Anyway, as long as you score, you deserve praise.

Second, what's your problem? Be objective when affirming your own advantages, and be more objective when analyzing problems. Many students like to say, "I was careless, and I miscalculated." I believe this is true, but have students ever wondered why they are careless? In fact, the root cause is still insufficient computing power. I can't help it if I don't learn arithmetic well in primary school. Calculation is also a kind of ability, which requires students to train repeatedly. When you find a problem, you should train yourself accordingly to prevent you from losing points on the same question in the next exam.

Third, sum up the psychology. Psychological factors are also a part of influencing test scores. For example, this exam has problems in the whole grade, and students will feel nervous when sitting in a strange classroom, which may affect the performance of the exam. This kind of problem cannot be solved in a short time after it is discovered. You know, the college entrance examination is not just a matter of disturbing class order. You may have gone to a school you have never been to, and it is almost impossible for you to know the classmates sitting around you. Therefore, students should learn to adjust themselves, and don't let these objective external conditions affect the performance of the examination level.

Again, mathematics is a reasonable subject. After you finish the problem, think about whether it makes sense for you to do so. Mathematics has three forms of expression, Chinese, symbolic language and graphics. If you can unify these three forms of mathematics in your mind, it means that mathematical thinking has been formed in your mind. In the process of learning mathematics, we should learn to listen, watch, draw, write and calculate, make full use of various senses and construct mathematical thinking, so as to learn mathematics well in senior high school.
