How to improve mathematics quickly in grade three? First, ensure the quality of lectures.
In order to improve math scores and ensure the quality of lectures, it is necessary to thoroughly digest and absorb what teachers say in class. The point to be emphasized here is that children should not be allowed to stay up late to do their homework. Many parents have to finish their homework before going to bed, no matter how tired or sleepy their children are. This is very undesirable. Inefficient study is a waste of energy and time. It is suggested to get up early in the morning to make up homework, so "going to bed early and getting up early" is in line with human physiological laws.
Second, be good at discovering mathematical laws.
If you want to improve your math scores, you must be good at discovering rules in the process of doing math problems. Don't always set a rigid formula, you can try to change your mind, which may bring you a different turn. In fact, mathematics is the same as other subjects. Just like Chinese, you can use other words instead, but the meaning has not changed, and the mathematical formula is the same. The final answer is one, but you can answer it in other ways, so you are good at discovering the law of solving problems in mathematics, and changing your thinking is also an effective way to improve your math performance.
Third, master the calculation method skillfully
There are some commonly used high-end methods for calculating problems, which can simplify the calculation process and improve the calculation accuracy. For example, when calculating the sum of geometric series, it is meaningless to memorize the result formula. Once the reminder changes, it is no longer just a geometric series, and the child may lose points. However, if children understand that the deep deductive method is dislocation subtraction and make flexible calculations, maybe this idea will be passed. This part of the study is very important for students who want to sprint full marks in the senior high school entrance examination.
Fourth, do more exercises.
The purpose of doing more exercises is to master the skills and tricks learned from practice. Different problems have different methods, and using different skills, especially the moving points in functions, is a hot topic now. Do more, but don't do too difficult questions, focus on learning. We should pick the wrong questions, especially those in large-scale exams, analyze the causes of the mistakes by returning to textbooks and solve the problems from the root. Redoing the wrong questions is a good way to check and fill the gaps, which can spend less time and solve more problems.
Extended reading: What are the skills for answering the final math questions in the senior high school entrance examination? First, pay attention to classified discussion.
Classification discussion is to test the accuracy and rigor of students' thinking, which involves this kind of questions, usually through the variability of conditions or the uncertainty of conclusions. Some problems, if we don't pay attention to the classified discussion of various situations, may cause wrong solutions or missing solutions. In recent years, using classified discussion to solve problems has become a new hot spot.
Second, the graphics or basic graphics needed to construct the theorem
In the process of solving problems, it is sometimes necessary to add auxiliary lines. Only one simple proof problem can be proved without auxiliary lines, and the rest involve adding auxiliary lines. The requirements for students to add lines in the senior high school entrance examination are quite high, but almost all of them follow the principle of constructing graphs required by theorems or construct some common basic graphs.
Third, learn to use the combination of numbers and shapes.
The idea of combining numbers with shapes refers to a mathematical idea that studies the relationship between numbers by using the properties of geometric figures to seek the solution of algebraic problems, or studies the properties of geometric figures by using the relationship between numbers to solve geometric problems. The idea of combining numbers and shapes skillfully combines quantitative relations with geometric figures and solves the problem.
Fourthly, apply the idea of equivalent transformation.
Transforming thinking is a basic mathematical thought to solve mathematical problems. When learning mathematical problems, we usually turn unknown problems into known problems, complex problems into simple problems, abstract problems into concrete problems and practical problems into mathematical problems. The connotation of transformation is very rich. Known and unknown, quantity and graph, graph and graph can all be transformed to solve problems.
