Four-leaf clover is produced by clover gene mutation, accounting for only one in 100 thousand. That is to say, among100000 alfalfa plants, you may only find one with four leaves, because the probability is too small. Therefore, the four-leaf clover is an internationally recognized symbol of luck.
How to study mathematics
As a subject with equal emphasis on knowledge and skills, the starting point of mathematics learning is to learn basic knowledge such as concepts, formulas, laws, properties and theorems, and the final result is to learn basic skills such as calculation, drawing and reasoning. However, according to previous teaching experience, some students only pay attention to knowledge learning, and may be familiar with mathematical concepts, algorithms, property theorems, etc., but they are at a loss when they encounter problems.
There is no way to start, and the typical knowledge is not known. The root cause of this phenomenon is that the eyes are superior and the eyes are inferior, thinking that understanding is everything and unwilling to practice. As the saying goes, science should be practiced more and liberal arts should be accumulated more. In fact, the effectiveness of mathematics learning depends not only on the classroom, but also on self-study.
Therefore, making full use of the afternoon study time to consolidate the problems learned on the day of practice is the key to improve mathematics academic performance. ? Contrary to the former situation, if we only pay attention to the mechanical training of solving problems and ignore the integration of knowledge points, it is difficult to achieve good academic results in mathematics.
In reality, some students write blindly when they know little about the content of the new lesson, and the basic skills of calculation and drawing are not solid enough because of cat-like practice. If you encounter problems similar to textbook examples or homework exercises, you can still complete them, but you feel helpless when you encounter a variety of new problems.
