1.
This book is organized into 144 small topics for learning, categorized into 'areas outside the curriculum' that are deemed appropriate for elementary school students to study, 'areas that are learned in middle and high school but where elementary school students can observe phenomena and understand theories', and 'areas that are concepts learned in the curriculum but require high-level problem solving'.
The 144 small topics are categorized based on criteria that students can easily accept, and since they are for elementary school students, the size of each topic is categorized relatively small.

2.
I have listed the breathing techniques that are actually suitable for studying.
It is divided into a total of 4 courses, and each course contains 36 topics.
The 36 topics are the amount to be studied over 6 months, with 6 topics per month.

3.
I have explained it in a way that it can be explained to elementary school students.
Course 1 has selected and explained topics so that anyone who has completed the 4th grade elementary school curriculum can understand them.
Likewise, you can study Course 2 if you have completed the 5th grade curriculum, and Courses 3 and 4 if you have completed the 6th grade curriculum.
Of course, in the 3rd and 4th courses, we also preview the middle school level, so we also included middle school level solutions.
The answers and explanations contain detailed explanations so that you can study on your own.

4.
Even for 5th and 6th graders, this is a program that allows for the greatest learning effect by completing all 4 courses in order from Course 1.
