Looking at the mathematics test questions of Hefei senior high school entrance examination in recent years, the guiding ideology of "paying close attention to the foundation, paying attention to the process, infiltrating ideas, highlighting ability and emphasizing application and innovation" will not change. The proposition will develop in the depth required by the curriculum standard. Therefore, it is particularly important and urgent to grasp the review direction of mathematics in the 20 13 senior high school entrance examination.

First, pay attention to the review of basic knowledge of mathematics.

Outstanding performance in the review of basic mathematics knowledge, basic skills, basic thinking methods and basic activity experience. As we all know, nearly 50% of the scores in the math problems in the senior high school entrance examination every year are an examination of basic knowledge. Therefore, in reviewing the basic knowledge, we must not relax our vigilance.

Mathematics in the 20 13 senior high school entrance examination will basically continue the difficulty ratio of the previous year, so it is very important to have a pragmatic foundation in the review process. Understand the concept thoroughly, and sort out the connections and differences between knowledge. Never blindly pursue off-topic, strange topic and difficult problem.

Second, strengthen the cultivation of mathematical ability and mathematical consciousness.

The basic abilities of mathematics mainly include spatial imagination, abstract generalization, reasoning and argumentation, operational solution, data processing and so on. Pay special attention to the examination of the main knowledge of junior high school mathematics; Check the internal connection of knowledge; A survey of mathematical thinking methods in junior high school mathematics: an appropriate infiltration of the process and inquiry learning ability. Comprehensive ability is mainly manifested in the ability to analyze and solve problems.

The examination of mathematics consciousness mainly focuses on the examination of mathematics application consciousness and innovation consciousness. The former requires students to use the mathematical knowledge, ideas and methods they have learned to build a mathematical model and turn some simple practical problems into mathematical problems and solve them. The latter requires the ability to comprehensively and flexibly use the learned mathematical knowledge and thinking methods to solve problems creatively. In short, students should be able to ask questions, understand and solve problems from the perspective of mathematics, communicate logically with people, and have a preliminary sense of reflection.

Third, grasp the distribution of examination content and allocate energy reasonably.

Mathematics in the senior high school entrance examination consists of three parts: number and algebra, space and graph, statistics and probability. Number and algebra account for about 50%, space and graph account for about 38%, and statistics and probability account for about 12%.

As can be seen from Table 2, the content of the annual senior high school entrance examination has not changed much, and candidates can allocate their time and energy reasonably according to their actual situation. Grasp the review direction and improve the review efficiency.

Fourth, pay attention to the changes in the exam instructions.

Every year's exam instructions are the direction of the senior high school entrance examination, so we must carefully study the exam instructions, pay special attention to the interpretation of the exam instructions, especially the newly added and deleted test sites, and must not blindly fight.

Five, put an end to some common problems

1. Thought does not attach importance to it. Because a lot of the content of the general review has been learned, many candidates have bad habits such as "don't want to listen", "just watch but don't write" and "just want to do nothing", thus ignoring the re-learning of basic knowledge.

2. The inspection is not detailed enough. Judging from the past experience of preparing for the exam, more than 30% of the points lost in the senior high school entrance examination are due to poor examination questions. Therefore, in the training of comprehensive questions, students should adopt the way of "looking at the questions first, then doing them", and gradually improve their ability to examine questions through training for a certain period of time.

3. Don't do the problem carefully enough. Carelessness, one small step wrong, the result is completely wrong, and more points are lost.

4. Ignore the classification of wrong questions. This leads to the phenomenon of "doing things repeatedly and making mistakes repeatedly" and "saying the wrong thing", and fails to properly handle the relationship between "understanding peace, doing right but not doing it, and doing right but not doing it".

5. I often don't have a good grasp of the exam time. There are three sentences that are of great reference value to our junior high school students: (1) Do what you do first, be right, the more the better; (2) Do the intermediate questions steadily and don't waste a point; (3) Giving up all skills (10%) is like "losing your car to keep your handsome" and giving up the math scores you can't get. In addition, candidates should also pay attention to the phenomenon that the answer is not standardized and the calculation ability is weak, which leads to the loss of points.

Sixth, pay attention to the adjustment of review mentality.

Finally, the teaching and research team suggested that all junior three students must actively cooperate with the school teachers to review, be diligent and inquisitive, and conscientiously do the following five words in the review process:

Check-check for loopholes and fill in the blanks with the exam outline.

Practice-practice purposefully

Correct-Reflection with Wrong Questions

Look-go back to the textbook with questions

Grand total-Use the summary method of the question.

Don't take a cursory look, but aim high. Attitude determines height, details determine success or failure. Power is the magic weapon to win, and precision is the core technology. I believe that students will achieve excellent results in this year's senior high school entrance examination.
