Multi-Thinking Era
Multi-thinking involves making comprehensive judgments from different perspectives, directions, and levels, thereby generating multiple approaches, methods, and solutions to address problems. This lays a solid foundation for decision-making choices. In today's rapidly evolving and ever-changing era of information technology, possessing the ability for multi-thinking is becoming increasingly crucial to cope with the constantly changing environment.

Mathematical Thinking Ability
Learning mathematics can cultivate the ability of mathematical thinking while the prerequisite for mastering mathematics is to have this ability at first. The so called mathematical thinking ability means correctly understanding a certain phenomenon and exploring its essence. It serves as the foundation for creativity, argumentation, and problem-solving not only in the study of mathematics but also in the learning process of historical and social phenomena.
With developed mathematical thinking ability, even when facing unfamiliar problems or phenomena, one can find connections with other elements, enabling analysis, solution, and explanation. Archimedes' discovery of buoyancy while bathing is not unrelated to this.

Establishing the Foundation for Mathematical Thinking Ability
“Classification”, “Measurement”, “Patterns”, “Shapes”, “Space”, “Numbers”, and “Calculations," are seven knowledge in mathematical domains and are subdivided into five Levels based on the developmental level of the brain at different ages.
Renowned Korean mathematician Professor Jin Yongyun participated in the entire process from planning to editing. This series is suitable not only for kindergarten children but also for elementary school students.

Vivid and interesting stories, lovely and bright painting style, let children unconsciously like math.
The stories are close to the lives of young children, attracting them to become the protagonists of the stories, experiencing interesting events in the book together, and encouraging them to think about and organize solutions to encountered problems.
By familiarizing themselves with the scenes in the book through illustrations, children can use these memories to find solutions when facing similar situations in the future.
