So I'll talk to you about review methods tonight.
Examination is different from homework logic:
Our exams are different from our homework. Some children's homework is ok, and the accuracy is quite high, but their exam results are not ideal. For example, after school, I will write my homework on the day I go home, but the exam is different. It is phased and comprehensive. For example, if you do your homework, you can read the information. If you can't, you can ask your classmates, but you have to rely on yourself in the exam. Also, when writing homework, the format may not be standardized, and it may not meet the standards, but the examination teacher will be very strict; In addition, some children are anxious about exams. Before the exam, mom and dad cheered their children up, but they didn't do well in the exam. Some children even have to go to the toilet before and after the exam to relieve stress and even affect their exam results.
That specifically involves the review of mathematics. I take Beijing Normal University Edition as an example, which is divided into four steps:
1 Return to books, organize chapters, conceptual formulas, property theorems, etc.
Just like building a house, whether the foundation of the house is solid or not. For example, in the review class, we ask our children to recite formulas, concepts such as monomials, polynomials and algebras, as well as the operation of powers and the multiplication and division of algebras. We must remember the square difference, complete square formula and deformation. Some children can memorize the complete square formula, but once they use it, they just don't need it. Because I am not skilled enough, I am afraid of making mistakes, so I use the most complicated formula to deduce it again, which is time-consuming and laborious, and always makes mistakes, and important formulas are even more unfamiliar.
For example, fill in the blanks with knowledge points:
Our children usually do a lot of big questions at school and get some points in the exam, but they make mistakes in choosing to fill in the blanks. After the exam, they tried to watch it. The mistake is that the concept is unclear.
For example, how to define parallel lines, how many property theorems and how many judgment theorems are there? What are the connections and differences between them? In this chapter, where must we add the words "in the same plane"? Parents can let their children look for it.
For another example, the chapter of triangle involves the relationship between three sides and angles, as well as the important line segments of triangle and their properties, and the properties of isosceles equilateral triangle. These are definitely alternatives to the final multiple-choice question.
There are several ways to prove congruence, and the common auxiliary line method is the idea of geometric proof.
2. Break through the questions and summarize and practice the common hot issues in each chapter.
Our science subjects, such as mathematics and physics, are all about problems, not just problems. We must understand our thoughts.
I often ask my children to do some sprint papers for the senior high school entrance examination, which are the questions and difficulties that most children have to take, the daily homework of the school and the weekly papers. You must analyze and classify the problems, and you can mark them with different pens. For example, questions 2 and 8 are a kind of questions, are they simplified evaluations or abnormal applications of formulas? Through this analysis, children will find that in fact, exams are repeated practice. This is a very efficient learning method.
3. Familiar with routines and patterns
Common models of parallel lines: pencil model and pig's trotters model. For example, I often tell you that when you meet an inflection point, you will make parallel lines.
The common types of triangular chamfering are: 8-shaped, dart-shaped and angle-folded.
Triangle congruence model: natural model of angular bisector, isosceles right triangle model, three vertical model, folding (symmetry).
Learning these models well is equivalent to taking a toolbox exam, which is very efficient. Compared with other students, it saves the process of derivation and is fast and accurate. Of course, the premise is to master the basic content and not put the cart before the horse.
If the child can do all the previous steps well, master the basic knowledge points and questions, and can't make mistakes in calculation, then there must be no problem in your exam, except that some schools originally required it to be difficult, such as the finale, which is not to do too much, but to refine it. After finishing, continue to repeat the exam, say your thoughts in your own language and find out the logical relationship inside.
Finally, children, our exam review is a huge project. The final exam is not a result, but every step of your review. Only when each process is completed can we get satisfactory results.
4. Insist on correcting the wrong questions
Bind the test papers of the whole semester together, spend half a day every week, correct the wrong questions, mark them with asterisks, and ask the teachers and classmates until they know, and continue to correct them next week to see if they really understand. For wrong questions, just like camels eating grass, children need to look at their ideas repeatedly to avoid repeating the mistakes of the same type of questions in the exam.
Finally, I want to share a scoring skill with you. Some children always make mistakes in their calculations. After the results came out, they always said that if I was good, I would do better in the exam than one of my classmates. Actually, it doesn't matter if I'm wrong. The key is your attitude towards the wrong question. You should analyze how it is wrong, whether the topic is wrong, whether the numbers are wrong, and whether the addition and subtraction symbols are wrong. After finding out the reason, do seven or eight related questions every day. If it's a problem with digital operation, find some. If the symbol is wrong, you can practice the symbol, such as this picture I uploaded.
In a short time, the number of calculation errors will be greatly reduced.
The above is the math review method I share with you. I hope every student can use it and get good grades in the final exam.
