In this era of liberal arts and science integration, elementary school math ultimately determines college acceptance!

This book is a revised edition of [Don't Let Math Hold Your Child Back].
Elementary mathematics focuses on numerical operations.
In this book, Jo An-ho, a math study method expert, explains the seven most important areas of elementary math, which can be considered the foundation of middle school and high school math, in an easy and fun way.
How should we approach elementary mathematics in this era of integrated liberal arts and science? The author emphasizes that the first step is to thoroughly master the following seven areas.

① Operations and speed of natural numbers ② Operation symbols ③ Operations and expansion of fractions ④ Area ⑤ Movement ⑥ Probability ⑦ Word problems

The number of children giving up on math increases rapidly when they reach fifth grade.
Then, when they get to middle school and high school, more than 90% of them give up on math.
If your child is in elementary school, it's not too late.
Let's first diagnose which areas our child is lacking in using the 'Grade-specific Test Sheet' included in the appendix of this book.
Then, you can look at this book to learn what and how to teach.
Parents will find practical [tips] that can be utilized through the link between the main text and the appendix test paper.

“Realistically, there is no way to get into a good university without being good at math.
The idea is not to foster a sense of crisis, but to face things as they are.
However, until now, children who have difficulty with math have given up on their dreams of going into science and engineering and gone to liberal arts departments, and through competition with other children who are not good at math, they have been able to get good grades and go to good universities.
But for current elementary school students, that is a long way off.
When current elementary school students advance to college, the path to escape will be completely blocked, as if they were to run away to the liberal arts if they were not good at math, due to the integration of liberal arts and science.
Policymakers say they're reducing the amount of math and making it easier, but I think they're going in the wrong direction and the perceived difficulty for children will actually increase."
---From the author's note

It has been the case up to now, but it is clear that if a child is not good at math in the future, all of their other strengths will be buried, and they will be relegated to the role of raising the grades of children who are good at math.

The best way is to strike before the question, "What can I use this for?" arises.
Until this question arose, the child desperately wanted to avoid math because it was difficult.
I haven't decided to give up on math yet, but I already hate it.
It's best if these questions don't come up, but if that's not possible, the need for mathematics should be communicated in advance on a regular basis.

In my opinion, the reason children struggle with math is not because the problems themselves are difficult, but because they lack a good understanding of the areas where they struggle and a lack of long-term solutions.
Children will have to study for at least 12 years before taking the college entrance exam, so we need to build a solid foundation so that it won't be shaken no matter how much the system changes.

If you are in 4th or 5th grade, it is already too late to go through all the math courses in order.
Solving any workbook will reduce efficiency and tire out the child by providing too much useless work.
Since parents cannot solve problems with existing workbooks or study materials, it is recommended that they edit and use them separately to fill in each gap.
