Basic operation, basic quantitative relationship; Basic graphic understanding and simple calculation of perimeter, area and volume; And simple algebraic knowledge.
Junior high school mathematics focuses on cultivating students' mathematical ability, including calculation ability, self-study ability, ability to analyze and solve problems, abstract logical thinking ability and so on. Content increase
Complex plane geometry knowledge, systematic learning algebra knowledge, using equations to solve practical problems; Number is extended to rational number and real number; There are simple linear functions and quadratic functions.
High school mathematics is the continuation of junior high school mathematics. The scores and roots of junior high school can be seen everywhere in senior high school, which requires students to be familiar with them. For example, the functions in junior high school are greatly deepened in senior high school and become basic elementary functions such as power function, exponential function, logarithmic function, trigonometric function and inverse trigonometric function. Plane geometry in junior high school rose to analytic geometry and solid geometry in senior high school. Therefore, junior high school mathematics is the foundation and plays a vital role in learning senior high school mathematics well.
High school mathematics is the improvement of junior high school mathematics. Mathematics in junior high school has been extended to senior high school, which has been improved in essence. One is abstractness. For example, junior middle school functions are concrete functions, and senior middle school functions are summarized by y=f(x). The functions, inequalities and equations in junior high school are relatively isolated, but in senior high school, they are unified in function. Equation is the zero point of function, and inequality is the range of independent variables when the function value takes a specific value. The second is comprehensiveness. For example, the operation of junior high school is relatively simple, while that of senior high school is much more complicated. The frequency of comprehensive questions in junior high school is not high, while in senior high school, with the deepening of functions, the single column of series and the birth of analytical methods, comprehensive questions will have a broad world with these as carriers.
The rhythm of high school mathematics is obviously faster than that of junior high school. Junior high school mathematics often stays on a certain knowledge point for a long time, and the same question type can give more time for repeated training. But high school mathematics is rich in content, and a trunk has many branches. For example, after the first year of high school, we will talk about sets, and then we will talk about functions, function definition ranges, function relationships, monotonicity, parity ... wave after wave, wave after wave, how can we leave too much?
The difficulty of high school mathematics is obviously greater than that of junior high school. With the growth of age, knowledge is enriched and content is broadened, which is also accompanied by abstraction and comprehensiveness. So it will be more difficult to learn math well in high school.
Judging from the scores, the college entrance examination is uglier than the senior high school entrance examination. Because the content of the senior high school entrance examination is not much, and the difficulty distribution of the senior high school entrance examination is 8: 1: 1, the emphasis is on the foundation, so as long as the basic questions are well done, you can get 120 points, and then you can get a little middle and high-level questions, so it should not be too difficult to get more than 130 points. I have taught two students in Class 20 14. One of them got full marks in the senior high school entrance examination and the other one got 144.
The college entrance examination is different. Because of its selection function, it is bound to be considered in the topic setting. Generally speaking, scores of 100, 1 10 and 120 are all acceptable. It's good to take 130, but it's even more difficult to take 140. The perfect score is chicken feather scale angle.
