Three Mathematics Books for Children (All Three Volumes) (Guomai Classics)

"Three Books on Mathematics for Children" is an extracurricular mathematics reading book written by the famous mathematics educator Liu Xunyu for middle school students aged 13-18. It consists of three books: "The Fun of Mathematics", "Mr. Ma Talks about Arithmetic" and "The Garden of Mathematics". The three books range from easy to difficult, from abstract thinking to problem-solving applications, to comprehensively cultivate the core mathematical literacy of students aged 13-18. "Mathematical Fun" What is mathematics? What's the use of mathematics? What mathematical ideas are contained in life? This book contains 11 articles published by the author in the "Mathematics Speech" column of the magazine "Middle School Students". It uses storytelling and interesting narratives to stimulate students' desire to explore mathematics. "Mr. Ma talks about arithmetic" This book fictionalizes the teacher character "Mr. Ma" and uses storytelling to explore more than a hundred common mathematical problems, including the catch-up problem, the problem of birds and animals in the same cage, the problem of running boats on flowing water, etc. It is both interesting and practical. "The Garden of Mathematics" This book uses easy-to-understand narration, starting from the motion of the train, and introducing concepts such as functions, limits, differentials, and integrals step by step. The originally abstract and boring mathematical terms are given a wonderful interest. Students who have studied elementary algebra and geometry can easily master it and can be used as an important self-study book. This edition is based on the original version of Kaiming Bookstore. Mathematics experts have been specially invited to review the errata, the charts have been accurately redrawn, and accompanying text notes have been added to make it easy to read.
