Have a comprehensive review plan for important knowledge, often tested in the exam.
Students should group related knowledge into each topic, with each topic they should do well in the exercises in that topic, specifically as follows:
Topic Reducing expressions and related problems: students must be able to reduce expressions containing roots and know how to answer the sub-questions of this type of exercise. In the 10th grade exam, this part usually occupy from 2 to 2,5 points. To do well in exercises related to homogenous transformation, students need to master the properties and operations of roots and practice skills in reducing expressions and solving equations. process, inequalities.
Topics on trigonometric systems in right triangles and Topics on circles: students practice their skills in solving geometry problems in a concise and accurate way. The exercises in these two topics usually account for 2 to 3 points in the 3,5th grade exam. To do well in the geometry exercises in the 10th grade entrance exam, in addition to memorizing the theorems, properties in textbooks, students need to pay attention to the method of thinking to find out how to solve each type of question, each type of exercise, for example equations to prove equality, prove relations, prove concurrency. alignment, method to find the maximum and minimum values of geometric quantities,…
Topics System of first-order equations with two unknowns – Solve problems by making equations, systems of equations and Topics of equations and systems of equations that students need to do to understand how to solve and argue some types of equations, systems of equations commonly encountered in the 10th grade exam and facilitate problem solving by making equations. Exercises on equations and systems of equations account for from 1 to 1,5 points in the 10th grade exam. To get high scores in these exercises, students need to master the skills of solving equations and systems of equations. in general as well as the ability to solve some system of equations of special form.
Solving problems by making equations or systems of equations usually accounts for 2 to 2,5 points in the 10th grade exam. This is not a difficult problem, but in order to get the maximum score, students pay special attention to doing it fully. enough steps and full exact condition for hiding. On the other hand, it is necessary to have the skills to quickly and accurately solve equations and related systems of equations.
Topics Functions and graphs students need to solve correlation exercises, graphs of first and quadratic functions. Exercises on functions and graphs usually account for 0,5 to 1 point in the 10th grade exam. To do well in functions and graphs, in addition to knowledge of graph functions, students need have a deep understanding of quadratic equations, Viet’s theorem and other related knowledge.
Topic Inequalities and Extremes: Students need methods to prove inequalities and solve problems about the maximum and minimum values of algebraic expressions. The exercise on inequality and extrema is a difficult exercise for fairly good students and usually accounts for 0,5 points in the 10th grade exam. To learn well the exercises on inequality and extremes, in addition to the knowledge Students need to pay attention to flexible and creative transformation methods applied to different types of algebraic expressions.
Read a lot of reference books
Just like Literature, read as many textbooks as possible on 9th grade Algebra and Geometry. You also choose to read from basic to advanced. The books have basic examples, scientific solutions, concise and clear explanations. From there you grasp the important ideas. As well as how to solve problems that you have not encountered.
Right now, the 4.0 technology era is developing widely. A lot of 9th grade math exercises and solutions are posted online. Learning 9th grade math online is also very useful. You can find information about Grade 9 Math for free or study online for a fee. Through this, you will practice and improve your learning efficiency.
Constantly searching and learning the ways of solving math problems of good students and teachers
Constantly researching and learning the ways of solving math problems of good students and teachers, and then choose for themselves the most standard method, suitable for the requirements of the topic. Only then will you be able to get a perfect score and take the opportunity to enter a public school in Hanoi.
Allocate time for exams reasonably
The 10th grade entrance exam is not only about taking one subject, but also having at least 1 subjects, even 2 subjects. Therefore, it is very important to allocate a reasonable time to study for each subject. You will not be able to study all subjects at the same time, which will cause boredom and stress. Therefore, it is necessary to allocate time for each subject as well as reasonable time for studying, resting and entertaining… The advice for you is to study in the morning, should not study for too long, time 4 to 45 Minutes for a subject is the most appropriate, take a 60-minute break before continuing to study.
Thoroughly study the theory of concepts, definitions, and theorems in each lesson, including algebra and geometry
As we all know 9th grade Math has 2 parts Algebra and Geometry. With the 9th grade math program, in the opinion of most of you who have been studying in 9th grade today, the Algebra section seems to be easier to “get points” than the Geometry part. You often have trouble with the Circle part. The main reason is that the way we draw the figure is not standard and inaccurate, leading to difficulty in determining the solution method for the required problem. For that reason, you often have a common mentality that you try to focus on studying the Algebra section carefully to “make up” for the score for the Geometry section! So is this the best way to get high scores in exams? My personal advice to those of you who have been – are – will be studying 9th grade Math is that you should try to find yourself the most appropriate method to improve your math problem solving skills because if you just practice Only a part of high school, the probability of getting a perfect score in the test is very low. You must have full knowledge of both sections, master how to solve all types of problems that appear in the most recent exams.
Find lots of materials from different sources for reference and practice.
Find lots of materials from different sources for reference and practice. Watch instructional videos to solve math problems that often appear in test questions of some good teachers with many years of experience in exam preparation across the country.
To do well in 9th grade math is not too difficult. What you need to do is master problem solving skills. You can practice solving problems from basic to difficult problems. But don’t give up because it’s easy to miss. Because there is a proverb: a hundred or not equals a familiar hand.
To do so, first try to solve all the basic problems in the 9th grade Math textbook. After you have thoroughly understood how to solve the basic problems. You should just move on to the advanced synthesis or math problems. Because if you jump right into a difficult problem, it will easily make you discouraged. Because maybe you can only solve half and stop. If you can solve it, it may take you a long time. In addition, as mentioned above, all easy problems are fundamental to lead to more difficult problems. Therefore, you should follow the math problem solving process from basic to advanced.
The practice of solving many problems from low to high helps them solve many different types of problems. Thereby helping you to be able to adapt faster when encountering new forms.
Need to practice problem solving skills from basic to advanced
In fact, it is not difficult to do well in Grade 9 Math in class if students have a reasonable method and practice. First you need to practice with math problems, the most basic types of problems in textbooks and workbooks. After successfully completing those types of topics, the next thing is to search for advanced topics, new and strange exercises in reference books to practice more. Doing so many exercises will benefit you a lot, helping you not to be confused and be able to solve them faster when encountering strange math problems in exam questions and tests.
Practice drawing skills for the geometry part
It is necessary to practice the ability to draw pictures, drawings need to be clear, accurate, careful and meticulous to be able to find a method of solving math problems in the most convenient, fast and effective way possible.
Drawing pictures is a basic skill to study well in 9th grade Math. In the lower grades, you have also experienced Math exercises related to drawing pictures. However, the level of abstract thinking is low. For Grade 9 Math is more difficult. You need to think more. There are many students who do well in Algebra. As for Geometry, it is quite weak. The main reason is still the ability to draw and think geometrically.
And one thing to admit is that Geometry is considered more difficult than Algebra. However, just pay attention and you can conquer Geometry easily. Start by practicing your drawing skills with clear, precise shapes. From there you will clearly see the connection of the segments, the corners. This will be of great help to them when looking for the solution to the picture.
Make a study outline
If you are sure to stick to the basics of the textbook, create your own review outline. The review outline is the systematization of basic knowledge, which must be memorized, into notes or tables. Making a review outline helps students have the most general view of the amount of knowledge to learn as well as the logic for each lesson. From there, a suitable study plan will be devised. This is one of the most effective 10th grade exam preparation methods.
Need to systematically and carefully memorize the math knowledge learned in grades 6, 7, 8
It is necessary to systematically and carefully memorize the mathematical knowledge learned in grades 6, 7, 8 especially the core knowledge in grade 9. All knowledge sections in math have continuity and tight logic. closely together. So if you lack basic knowledge in the lower grades, it is very difficult to do well in math in 9th grade, especially the knowledge parts of 8th grade such as polynomial multiplication and division, algebraic fractions, triangles. Similarities, circles are the most basic and most important knowledge to do well in grade 9 math.
