“≪Elementary Geometry in One Book≫… basically, we tried to include as much of the core know-how of learning geometry that has been tested and successfully supplemented in the educational field for a long time for children who have difficulty with geometry, children who are good at solving problems but do not have a clear concept of geometry, and children who need a sense of geometry and thinking skills in a short period of time.” - From the author’s preface

Lay the foundation for middle school geometry with 52 essential topics you need to know!
A 4-step study plan to become stronger in math shapes!

Step 1: Systematic Systematic Learning
This book contains the scattered, six-year elementary school geometry learning content in one volume.
You can study concepts step by step, from the basics of points, lines, and planes to advanced problems in three-dimensional shapes.
This learning pattern, which is organized step-by-step into one book due to the distinct nature of mathematics study, is a very useful learning method for students who lack the basics of geometry.
Furthermore, it will be very helpful for students who have organized elementary geometry and are about to enter middle school.

Step 2: Various concept manipulation activities
There is a limit to understanding the essence of shapes by only thinking about them, such as measuring, drawing, and making them.
In middle school, everything is logical and abstract concept learning is the main focus, but until elementary school, it is necessary to understand through concrete activities.
For elementary school students in the concrete operational stage, activities that involve drawing and manipulating shapes, rather than just solving problems, will be a very vivid experience.
Through these activities, studying shapes becomes more familiar and your sense of shapes is renewed.

3-step in-depth concept learning
Rather than just memorizing the formulas, it is more important to understand the hidden meaning behind the concepts and how the formulas were derived.
Especially in middle school, problems such as congruence, similarity, and proof of geometric shapes that children have the most difficulty with cannot be solved by memorizing formulas alone.
Even if you forget the formula, you can say that you have properly learned the concept only when you can reconstruct the formula.
This book asks the question "why" about important concepts.

Step 4: Developing Shape Sense and Thinking Skills to Improve Problem-Solving Abilities
This book covers a total of 52 themes, focusing primarily on concepts that students find difficult and problems that they frequently make mistakes on.
In particular, we have placed a large number of problems that can develop the geometric sense and thinking skills necessary to solve geometric problems, thereby helping to improve the problem-solving skills of friends who are weak in geometric problems.
You will come to realize that learning shapes isn't just about solving a lot of problems; there are times when you need an intuitive sense of shapes.
