《A Complete Guide to Elementary Math, Connecting to Middle School Math》
Elementary school math is the foundation of middle school math!
Quickly cover only the content needed in middle school!

■ Was elementary school math difficult? It's okay! You can start studying now.
Mathematics is a subject with a strong systematic structure, with many units connected from elementary school mathematics to middle school mathematics.
However, because middle school mathematics has a broader range of numbers and a larger learning volume, there is not enough time to review elementary school mathematics whenever a learning deficit occurs.
Therefore, before studying middle school math, it is very important to first review and move on from elementary school math.

Was elementary school math difficult? Don't worry.
Because you can organize it quickly with this book!

■ There is no time to review content that is not used in middle school math!
Teacher Lim Mi-yeon, author of “Busy Middle School Math,” who has taught elementary, middle, and high school students in Daechi-dong for over 15 years, said, “The elementary school comprehensive workbooks on the market contain too much material because they cover all of elementary school math.
“A thick, comprehensive workbook can be used like a dictionary, but for busy first-year middle school students, the sheer number of concepts and problems can be overwhelming,” he says.
So, in academies that are known for teaching well, they select only the necessary parts of middle school math from a comprehensive workbook and train them.


■ Let's quickly organize only what is needed in middle school math!
If you are a busy prospective middle school student, rather than skimming through all of the elementary school math content, quickly organize and move on to only the content that connects to middle school math!
'Busy Elementary Math Complete Guide' is a book that selects only elementary math that leads to middle school math, following the secrets of a well-taught academy for busy prospective middle school students.
We boldly omit elementary school math content that is not necessary for studying middle school math, and quickly skim over less important parts by compressing them.
However, we have structured it so that you can study more by reinforcing the important parts used in middle school math!

■ Study knowing why it is important and how it leads to middle school math!
This book is organized into four areas (numbers and operations, shapes and measurements, regularities, and data and possibilities) regardless of grade level.
And for each unit, we show you how what you learned in elementary school connects to middle school math.
If you realize how important the work you're doing now is in middle school math, you'll gain the power to organize your concepts and solve problems on your own!

■ Teacher in the book!
'Busy Tips' and Hints from Padok-i Existing comprehensive books only compile vast amounts of knowledge, but do not provide methods for studying it.
So, I often relied on my teacher.
However, this book contains detailed study tips as if the teacher were giving you face-to-face advice.
Each concept at each stage is accompanied by friendly explanations and 'tips' containing the know-how of a renowned instructor, so you can easily understand it even if you study on your own.
You can also reduce calculation errors with the helpful hints provided throughout the book.

■ If you can solve the 'passing problems', you're ready to study middle school math!
At the end of each unit, we provide review methods based on the number of 'passing problems' and answers you got right.
Solve problems and review elementary math effectively at your own level.
If you can solve all the passing problems, you are ready to study middle school math.

Middle school math... just thinking about it makes you anxious, right? But don't worry, if you have a solid foundation in elementary school math, you'll be able to do well in middle school.

'Busy Elementary Math Complete Guide' will help busy middle school freshmen.
Use this book to review and master essential elementary math concepts!
