Description: Based on the renowned Encyclopaedia Britannica published by Encyclopaedia Britannica, Inc. of Chicago, USA, this book brings together the essential curriculum content that Korean elementary school students need to know, organized into a clear system of learning. Rather than separating the humanities and social sciences from natural science, the book presents comprehensive knowledge on each topic, helping to nurture creative learners who possess both humanistic imagination and an understanding of science and technology. Instead of relying on lengthy, dry text, the book presents a large amount of information through engaging visual images. The infographic at the beginning of each volume summarizes the core content through diagrams and illustrations, sparking readers' curiosity from the very first page. The main comic strips, which explain learning content in a fun and accessible way, along with a variety of vivid photographs, help readers absorb information quickly and remember it for a long time. Rather than simply listing fragmented facts, the book portrays its comic characters pursuing positive values based on what they learn and experience. Readers will encounter stories that value the environment, respect differences, and consider the greater good of humanity.
