Description: Based on content from the Encyclopaedia Britannica, published by Encyclopaedia Britannica, Inc. in Chicago, USA, this book compiles the essential curriculum knowledge that elementary school students in Korea need to know into a systematic learning structure. Without separating humanities/social studies from natural sciences, it covers comprehensive knowledge related to each topic, helping to nurture creative talents who possess both humanistic imagination and an understanding of science and technology. Rather than relying on long, tedious text, the book organizes a large amount of information into visual images. The infographic provided at the beginning of the book summarizes the core content of the volume through diagrams and illustrations, sparking readers' interest. The comic-style main text, which explains the learning content in a fun way, along with colorful photo images, will also help readers quickly absorb information and remember it for a long time. Furthermore, rather than simply listing fragmented pieces of information, the book depicts the comic's main characters pursuing positive values based on the knowledge and experiences they gain. Readers will encounter stories that cherish the environment, respect differences, and consider the common good of humanity.
