202 1 mathematical orientation of college entrance examination;

It is mainly the change of the scoring rules of multiple-choice questions. Compared with the 2020 college entrance examination I, the multiple-choice questions are changed from 3 points to 2 points, which reduces the speculation of candidates' scores; No longer draw "key points", increasing the coverage of knowledge; Multi-point connection with advanced mathematics.

Pave the way for higher mathematics learning; At the same time, new types of questions, such as logical reasoning questions and conclusion open questions, have appeared, which further clarify the importance of logical reasoning literacy and the necessity of mathematical knowledge accumulation; In addition, it also reflects the integration of interdisciplinary knowledge and strengthens the penetration of subject knowledge.

The proportion of basic mathematics questions in college entrance examination papers;

Basic questions account for 70%, 20% are medium, and 10% is difficult. In fact, there are still some differences between liberal arts and science. But in general, it is 7:2: 1, the basic questions are 70%, the intermediate questions are 20%, and the difficulty questions are 10%. But the college entrance examination is different every year. For example, it will be easier and harder year by year, so it will eventually be around 10%.

Keep the structure stable and highlight the mathematical characteristics;

The examination paper continues the overall style of mathematics subjects in Shanghai college entrance examination. The number of questions, the types of questions and the structure of questions remain stable, and the examination content covers the backbone knowledge of five major sections, such as equation and algebra, function and analysis, graph and geometry, data arrangement and probability statistics, and number and operation.

Based on the basic knowledge, examine the subject ability;

Based on the basic knowledge and skills of the subject, the examination paper requires candidates not only to master the general methods of mathematics, but also to have good mathematical intuition and understand the essence of mathematics. For example, the triangle area in the fill-in-the-blank problem, the minimum value of the sum of series, the trigonometric function problem in the multiple-choice question, the inequality problem and so on.

Attach importance to core literacy and highlight learning ability;

Many questions in the examination paper not only examine the candidates' basic knowledge and subject ability, but also highlight the examination of mathematics core literacy and learning ability. For example, the finale question designs three progressive questions by introducing a new concept related to function, which requires candidates to have an essential understanding of the definition from the perspective of number and shape on the basis of reading the definition.
