Features: This series has the following characteristics:
(1) Scientificity. It aligns with textbooks and goes beyond them. The knowledge points in each book are based on the teaching syllabi for primary school subjects and supplement a large amount of extracurricular knowledge. According to the age characteristics and educational principles of primary school students, the content is arranged step by step to help them master basic knowledge and learning methods.
(2) Diversity. Based on the predictions of educational institutions regarding future reforms and developments in primary education, as well as the diverse learning needs of primary school students, this book incorporates some new research findings in psychology and pedagogy, giving it a certain flexibility and choice.
(3) Informational. The book selects some knowledge related to textbook content, reflecting the latest achievements in science and technology in China and the world (e.g., the human-concerned environmental and energy issues), to broaden students' horizons, expand their information intake, and cultivate their ability to understand and adapt to the future world.
(4) Comprehensiveness. It emphasizes the intrinsic connections between disciplines, the links between knowledge and society, and the connection between students and knowledge.
(5) Fun. Adhering to the principle of "learning through play," the book is equipped with a large number of illustrations and graphics, using various forms such as games and storytelling, allowing primary school students to learn knowledge in the best state of mind. This book presents a colorful world of knowledge to primary school students who are about to enter the 21st century, encouraging them to explore this world! Guided by the spirit of "learning through play," it fully supports the current reforms in primary school classroom teaching. With an aesthetic sense, it carries many important mathematical concepts for upper primary grades. While presenting 20 mathematical stories and problems to young readers, it also harbors the ideal of guiding their eyes beyond Earth, into the boundless vastness of outer space. This book is suitable for primary school students in the fifth and sixth grades of five-year and six-year programs.
Indeed, in the previous fun math books, young readers have learned many interesting mathematical facts, but they only have isolated, individual mathematical concepts and have not yet grasped the concept of "comparison." Young readers have developed preliminary ideas about the transformation between finiteness and infiniteness, but they have not yet defined the "limit" concept of this transformation. Young readers have begun to learn how to use drawing tools such as rulers, triangles, and protractors to create simple geometric shapes, but they have not yet learned how to use a compass to draw circles and conduct aesthetic education through the simple curve—circles. In terms of forming the concept of "relationship" through the ratios of numbers, the areas of shapes, and the volumes of geometric figures; in terms of forming the concept of "functional relationships" through drawing graphs of direct and inverse proportion functions, statistical charts, and verifying Euler's formula, this book hopes to help young readers achieve a significant "leap" in their understanding. This book is closely linked and complementary to the previous math books. Later, it will integrate the mathematical knowledge of the primary school stage into a whole, forming a comprehensive and dialectical mathematical concept, allowing primary school students to develop comprehensively through these mathematical activities. We hope this book becomes a trusted guide for students, parents, and teachers.
