There are students who have solved a lot of math problems and their grades continue to pause in a certain section. The
calculation exercises have been sufficient and several question books have been solved, but there is insufficient time in the exam or mistakes are repeated during the last calculation.
In such cases, simply solving more problems may not be enough.
This is because the moment we look at the problem, we need training together to decide which concept to come up with first and which method to choose from among the different solutions.
Today, we are introducing Kim Hee-sun Mathematics School , which teaches the order and judgment process of looking at problems more important than classes that increase calculations.
What is Kim Hee-sun Mathematics School like?
Kim Hee-sun Mathematics School is a specialized mathematics school located in Ilsan Plaza Room 302, 181 Gangsong-ro, Ilsandong-gu, Goyang-si, Gyeonggi-do.
The core of what Kim Hee-sun Mathematics School thinks is important in class is simple.
Mathematics is not just about calculations, it's about deciding what to do first.
As soon as you see a problem, write a random expression and start the calculation, the solving process can be lengthy. On the other hand, if you look at the form and condition of the problem first, you can quickly narrow down the formulas and concepts you need to use.
Kim Hee-sun Mathematics School teaches students to think about problems in the following order.
This is a way of looking at the structure of the problem first, selecting the necessary concepts, then proceeding with the calculation, and finally checking the signs and conditions.
This is not just a technique for getting the answer right, it is a training exercise for determining the direction of solving a new problem on your own.
Why is judgment more important than calculation?
One of the most common habits when studying math is to start moving your pen as soon as you read the problem.
It can be released quickly in familiar types, but it is easy for the pool to lose direction if the expression is slightly different or if several concepts are mixed.
If you start with a calculation without finding the essence of the problem, you may lengthen the expression you don't need, miss the sign in the middle, or lose the formula you know at the right moment.
At Kim Hee-sun Mathematics School, we view these solutions as simple, repetition-oriented studies, and train the elements to look at before solving problems.
For example, in expressions with radicals, we first check to see if there are parts that can be grouped into the largest squares, rather than just decimal factors.In the
quadratic equation, we do not use the quadratic formula directly, but first determine whether it is in a form that can be factored into. The
quadratic function confirms the relationship between the direction, axis, vertices and signs of a graph before entering complex calculations.
The accumulation of these judgments reduces the solving time and simplifies the calculation process.
What is the three-step process of Kim Hee-sun mathematics school?
Classes and textbooks at the Kim Hee-sun Mathematics School largely divide the problem-solving process into three stages.
Step 1, first explore the shape of the problem?
The first step is to look at the internal structure without reacting directly to the appearance of the problem.
Determine which sections are associated with which sections, whether they have recurring forms, hidden squares, or common factors.
Even complex-looking problems can be much simpler in actual calculations once the core structure is discovered.
Therefore, reduce the habit of writing down problems as soon as the student sees them, and instruct them to observe conditions and forms first.
Step 2, Select the appropriate solving tool?
Once you have identified the structure of the
problem, then select the most appropriate concept and formula.
Even a problem like
can be solved in several ways, but accuracy and time management are important in the exam.
The process of determining whether to use
factoring, use the quadratic formula, apply the multiplication formula, or modify the expression and then calculate it is necessary.
Kim Hee-sun mathematics school doesn't just memorize formulas, but connects them to which formulas to use when.
Step 3, check where mistakes occur?
The final step is to organize the calculations and check where mistakes are likely to occur.
Identify frequently missed elements of the test, especially signs, domains, conditions of radicals, units, and orientation of graphs.Knowing the
pool and often losing points in the last row, it is important to train the calibration as a separate habit.
How will 25 years of field experience translate into your lessons?
The orientation of the Kim Hee-sun Mathematics School is based on the students' solving process for a long time and their direct observation of incorrect answers.
If you look at the problems that students often get wrong, it is not just because they don't know the concept that they are wrong.
You know the
concept, but often you don't find it in the problem, you choose the wrong formula to use, or you miss the sign in the last step of the calculation.
Kim Hee-sun mathematics school analyzes the causes of these repeated wrong answers and reflects them in the class and pool description.
Typically, we will break down how to simplify the form of radicals, how to find the square number structure, how to judge the range of irrational numbers between integers, and the check process to reduce sign mistakes.
This is to help
students identify specifically which stages of their judgement caused the problem, rather than simply saying “I made a mistake.”
Middle School Third Grade Course
Kim Hee-sun Mathematics School focuses on the first semester of junior high school and the flow of connection from square root and real number to quadratic function.
junior high school math contains many core concepts that lead to high school math.
square roots and real numbers require expanding the number system and understanding the properties of irrational numbers.
Calculation of expressions including radicals requires the ability to find the square number structure and simplify the expression. In multiplying and factoring
polynomials, it is important not only to memorize formulas, but also to quickly distinguish the forms of expressions.In the
quadratic equation, the appropriate solution must be selected between the factorization and the quadratic formula, and in the quadratic function, the relationship between the equation and the graph must be understood together.
Kim Hee-sun mathematics school explains how the concepts learned earlier are used in high school mathematics with the following units rather than teaching each unit as separate contents.
What study do you need for a student who stays in the 80s at 70 points?
Up to a certain level, you can increase your score by just memorizing concepts and solving repetitive problems.
However, students who stay in the 70s and 80s often lose points due to similar causes.
If easy problems result in computational mistakes, unfamiliar expressions, you may not be able to use the concepts you know, or you may be spending too much time on one problem.
Rather than increasing the number of questions unconditionally, these students need to identify the process in which the wrong answer occurred.
You need to make sure that you did not know the concept, that you did not recognize the form of the problem, that you chose the wrong formula, that you missed the sign or the calculation.
Kim Hee-sun Mathematical School instructs students not only to check the result of the wrong problem, but also to examine at what stage of the pool the judgment was wrong.
This adjusts the learning direction to avoid repeating the same mistakes in similar types.
High School Mathematics How do middle school concepts connect?
Among students stuck in high school mathematics, there are times when the basic computational and functional concepts of middle school courses are not sufficiently organized, rather than the higher concepts themselves.
Even seemingly complex high school problems are often used in actual solving processes such as factorization, linear equations, square roots, Pythagorean theorems, and quadratic functions.
Kim Hee-sun Mathematical School Campus examines what the middle school concept is based on even when analyzing high school fundamentals.
In particular, in order to solve 3-point questions quickly and accurately, it is necessary to train yourself to correctly connect basic concepts rather than focusing only on difficult problems.
is characterized by teaching students not to approach high school problems too hard, but to use the middle school concepts they have already learned to simplify the structure of the solving.
materials and QR videos?
Kim Hee-sun mathematics school utilizes learning materials that allow students to quickly identify obstacles rather than simply showing the correct answer and the entire solution.The
manual reflects step-by-step the process of navigating the problem's structure, selecting the tool to solve, and checking for mistakes.
also links QR video content to identify the key judgment process for each question. The
video focuses on explaining what concepts the student should come up with first and where the pool should be oriented, rather than how to solve the whole problem from start to finish.
This is a way for
students to watch the video and then give a hint of the first step so they can continue solving on their own.
Kim Hee-sun Mathematics SchoolWhat kind of student is it suitable for?
Kim Hee-sun Mathematics School can help students with the following concerns.
Students who have studied the concept but are difficult to apply to problems, students who start counting as soon as they see a problem, students who have a long time to solve and insufficient time for exams, students with repeated signs and computational mistakes, and students who need to connect junior high school math with junior high school courses.
is also suitable for students who want to understand specifically why they are wrong rather than just checking the correct answer.
Studying math is not only about the number of times you have solved a lot of problems.
Even if you look at a problem like
, how quickly you can discover the core structure, choose the right concept, and reduce mistakes is linked to your actual test score.
Where is Kim Hee-sun Mathematics School located?
Kim Hee-sun Mathematical School is located at 181, Gangsong-ro, Ilsandong-gu, Goyang-si, Gyeonggi-do, 302 Ilsan Plaza.
For class content, textbooks, counseling, and registration details, it is recommended to contact Kim Hee-sun Mathematics School directly.
Communicating the current grade and grade of
students, as well as the types and habits that often go wrong, as well as their learning goals, together can help with more specific counseling.
Kim Hee-sun Mathematics School Q & A
Q1. How does the Kim Hee-sun Mathematics School Campus teach?

Finishing
When math grades are stagnant, it is easy to think of a lack of math practice.
If you are wrong because you know the concept but fail to apply it to the problem, or fail to select the appropriate solution, you need to revisit how to study.
Kim Hee-sun Mathematics School proposes judgment-oriented math learning that first identifies the form of the problem, selects the necessary concepts, and checks the pool to the last stage of mistakes.
If you are a student who wants to strengthen the fundamentals of middle school mathematics and make a natural connection to your high school course, your current pool can be a good place to start by examining your habits.
