The secret behind the top 3 powers in Daechi-dong's college entrance exam!
Superlattice Mathematics Lecture by Seungjae Ryu, a 28-year veteran math instructor.

To be clear, third grade math is not just a single grade curriculum.
'Conceptual mathematics', which begins in earnest in the third grade of elementary school, is a decisive turning point that dominates middle and high school mathematics and the starting point that will change the landscape of college entrance exams.
Depending on how you learn during this period, you may either grow up to be a 'child who excels at math' or, on the contrary, you may remain a 'child who gives up on math'.
Even the college entrance exam scores and success or failure in college admission are clearly divided.
In this educational climate, a children's education book has been published to serve as a compass for parents to help their children avoid getting lost when preparing for college entrance exams.


"Elementary 3rd Grade Math Camp Responsible for Entrance Exams" is a book written by Ryu Seung-jae, a math expert with 28 years of experience teaching students at various levels from elementary school to high school and countless practical cases, that teaches methods for building "math confidence," which is the core of elementary school study psychology.
The author emphasizes that “it is not the ‘head’ but the ‘direction’ that determines a child’s math performance, and the way they understand math, their attitude toward solving problems, and the habit of consistently maintaining it are what make for a top-tier CSAT score.”
In fact, the author confirmed through hundreds of cases that the common first hurdle for children who struggle with or give up on math was 'third grade math.'
Third grade is a time when children's math becomes fixed in a memorization-based manner, without parents' intention, and when children's understanding of math concepts is put to the test as the curriculum becomes more in-depth.
This book is a practical manual that will help you not miss that crucial moment.
This book will provide accurate learning standards and directions for parents who feel their children's math skills are wavering, parents who are confused about whether advanced or advanced learning is right for them, and parents who want to nurture their children's self-esteem as well as their grades.

If you have a solid foundation in third grade math, you will be more likely to continue to do well in elementary school math.
If you look at the advanced textbooks on the market, you will find that, strangely enough, the third-grade workbooks are the most difficult.
Because in the third grade, almost all concepts of elementary math are learned, and the advanced textbook contains advanced content that covers the entire elementary school.
Therefore, it is important to fully understand the third grade math concepts based on the textbook.
If you can digest the advanced textbooks on the market based on this, starting from the 4th grade, advanced math learning will become easier as if you are reviewing what you have already learned.

Having taught children for many years, I have realized that there is a clear difference between those who achieve overwhelming grades in high school and those who do not.
These days, school district math tests have become so difficult that even teachers are amazed.
It's hard to solve them all within the time limit.
Yet, what special abilities do these children possess that consistently achieve top grades? Based on 27 years of experience, I'd like to unravel the seven defining characteristics of children who excel at math and those who struggle.

Children who are good at math have many strong math-related brain connections.
As we study, understand new concepts, and review them, new brain connections related to those concepts are created.
The concept here corresponds to neurons, which are nerve cells in the brain, and the network can be likened to synapses that connect neurons to each other.
Children who are good at math have these concepts so firmly stored in their brains that they can pull them out instantly, like pulling something out of a drawer, whenever they need them.
To do this, consistent practice and repeated review are essential.
--- From "Part 3: Mathematical Aptitude: It's Not Innate, It's Made"

If your child never lets things slide and instead keeps asking "why?" questions, that's a very positive sign! Children who excel at math are meticulous enough to understand and convince themselves before moving on to the next step.
Parents should not be bothered by the "why" questions their children ask, but should become math exploration mates who help them find the reason until the end.
Developing the habit of frequently asking your child "why" in everyday life is a very effective way to develop their logical thinking skills, or mathematical intelligence.

If you want your child to develop a deeper understanding of math and develop the ability to think independently, writing can surprisingly be a powerful tool.
To write, you need to organize the thoughts in your head and arrange them logically.
This process is very similar to the thought process we go through when solving complex mathematical problems.
Among the writing methods specifically related to mathematics, there is something called a math journal.
A math diary is an activity where you organize the math content you learned that day in your own way.
Just like a diary where you record your daily routine, you take what you studied in math out of your head and write it down.
--- From "If Studying Math Was This Fun"

No matter how quickly other children seem to be moving ahead, you must never waver.
We need to proceed slowly at a pace that our children can fully understand and digest.
And you shouldn't just force your child to study.
It is essential to create space for children to breathe, whether it be reading books, writing, engaging in arts and physical education, or having fun playing with friends.
These diverse experiences will provide your child with a powerful internal motivation to overcome the difficult teenage years and study for their future when they reach middle and high school.
This does not mean that you should completely neglect your child.
It is fundamental to teach the correct math study method discussed in this book step by step and to create good study habits.

In fact, when teaching math to children, a situation suddenly arose where the children had to study on their own.
Because the newly purchased apartment was too far from the academy it was running.
As the moving date approaches, I realize that my children will no longer be able to come to the academy and study with me, and I feel a strong need to help them develop the ability to study on their own.
So I started teaching my children step by step how to study on their own.
Of course, we later decided through a family meeting not to move and to continue living in our current place, but in any case, that situation was a great help in accelerating the children's independent studies.

--- From "To the younger mothers as a parent of three children in middle and high school"

Sometimes, mothers may introduce more difficult terms or definitions that they know, which can be confusing for children and may involve concepts they haven't yet learned.
For example, in the case of a right angle, later on when you learn about angles, you can define it as 'the angle formed by two straight lines that is 90°' or 'the angle formed when one straight line meets another straight line and the adjacent angles are equal', but in the third grade of elementary school, where you haven't learned about angles yet, you define it as the angle formed when you fold a piece of paper twice straight.
Therefore, rather than explaining it using the definitions that the mother knows, the child should use the easy definitions presented in the textbook so that the child can understand the concept without confusion.
