A classic textbook I encountered for the first time,
How to learn interestingly and develop your thinking

Into a 'writing and learning class'
100-Day Literacy & Thinking Skills

“The best way to keep the classics close is to read the sentences and copy them by hand.”

Copying famous quotes → Wisdom of the classics → Opening the mind → Reading essential classics → Media convergence learning

These days, experts in the Korean education field are focusing on the value of transcription, analyzing it not as a simple copying but as a process of structuring the flow of thoughts into language.
However, most manuscripts remain mere collections of good sentences, and have the limitation of failing to show how those sentences can be expanded through thought and learning.

The new book, “Essential Classics for Teens: Learn and Write in 100 Sentences,” stands out in that respect.
This book focuses on 'how to think and write' rather than 'what to write'.
It is a reinterpretation of the classics as a ‘class to learn through writing’ rather than a book to simply read.
This book, which reflects the latest curriculum, contains 100 carefully selected famous sentences from 33 essential classic textbooks, ranging from Eastern classics such as The Analects of Confucius, The Tao Te Ching, and The Shepherd's Heart to Western humanities and literature classics such as Demian, Les Misérables, The Little Prince, and Silent Spring.
This is a new type of growth notebook where reading and writing, thinking and expression are naturally connected within the time frame of 'Complete one sentence a day for 100 days.'
The structure, which faithfully reflects the latest curriculum, not only fosters literacy, thinking, and expressive skills emphasized in the Korean language performance assessment, but also helps young people immerse themselves in the world of classics.


The author of this book, Park Gyun-ho, is a teacher with over 30 years of experience and a classics expert who has consistently researched classics interpretation and reading methods suited to the level of young people.
Through numerous educational books, including 『Reading the Unclassical Classics』(2018), 『My First Classic Reading Class for Teenagers』(2021), and 『World Classic Travel Troupe』(2023), he has consistently delivered the message that "classics are not books of the past, but mirrors that reflect me today," by explaining classics in an easy and interesting way.
This new book, “Essential Classics for Teens: Learn and Write in 100 Sentences,” is also an extension of that.
The key to this new book is not simply reading the classics, but transcribing each sentence into your own hands and connecting it to your own life.
This is what the author calls "study that teaches me," and it is the most accurate answer that classics can provide to modern youth who lack time for deep thought and self-reflection.
“Classic sentences, even as time passes, still lead us to better choices and serve as keys that open the door to new ideas.” This book began with that belief.

One sentence a day,
A must-have classic for teenagers: "100-Day Growth Notes"
_Three-dimensional learning completed through expansion of thinking

“If you read and write one sentence at a time for 100 days, the sentence will soon become an idea.
“Thoughts lead to language, and language leads to attitude.”

"Essential Classics for Teenagers: Learn and Write in 100 Sentences" is a collection of 100 sentences from 33 essential textbook classics organized into five themes (the power to build oneself, the courage to face the world, how to connect hearts, reading the world, and discoveries on the road) tailored to the growth stages of teenagers.
It presents a concrete learning structure called "Complete One Sentence a Day for 100 Days" so that students can utilize it in both school classes and daily life, and expands their thinking through the following three-dimensional corners.
It begins with a "classic line" that captures the essence of the work, followed by "classic wisdom" that interprets the thoughts contained in the sentence in today's language, "think about it" questions that expand thoughts, and "today's mission" practical tasks that put what you've learned into action.
As you write a sentence, you will experience that it becomes your thoughts, thoughts become language, and language eventually becomes your attitude.
Additionally, the 'Reading Classics' corner, which explains the background and theme of each classic, includes 'video QR' links to documentaries, lectures, interviews, etc.
Classics, previously learned only through text, can be combined with visual materials to provide a three-dimensional understanding of the historical context and humanistic significance of the works.


This structure will not only simultaneously cultivate literacy, thinking, and expressive skills, which are emphasized in the Korean language proficiency assessment, but will also be a useful tool for students who do not know how to read classics and students who are struggling with preparing book reviews and essays.
In addition, it is highly useful for teachers as a supplementary teaching material and for parents as a medium for studying classics with their children.
Through this process of translating the language of the classics into their own language over 100 days, students will read, write, think, and create their own sentences.
After 100 days, those sentences will accumulate and become the power that fills a person's inner self. Isn't that the true meaning of studying the classics?
