Description: Based on materials from the Encyclopedia Britannica Inc. of Chicago, USA, this book organizes essential elementary school curriculum content into a systematic learning structure. Without distinguishing between humanities/social studies and natural sciences, it comprehensively covers knowledge related to each topic, helping to nurture creative individuals with both humanistic imagination and scientific understanding. Rather than relying on lengthy, dry text, the book presents large amounts of information through visual imagery. The infographic at the beginning of the book summarizes the core content through diagrams and illustrations, sparking readers' interest. The comic-style main text and colorful photographs also help readers quickly absorb and retain information. Beyond simply listing fragmented facts, the book portrays its comic characters pursuing positive values based on what they've learned and experienced. Readers will encounter stories that cherish the environment, respect differences, and consider the common good of humanity.
