Improving Fun Mathematical Thinking for Primary and Secondary School Students (Four Volumes)

This is a set of mental arithmetic guides that can help children quickly improve their math scores. This book mainly covers mathematical knowledge points in primary and secondary schools. The example explanations in the book combine a variety of mathematical concepts and solution solutions to help children understand mathematical principles, develop logical thinking habits in mathematics, and stimulate children's own initiative. At the same time, for the after-school exercises in each unit, the author carefully provides "slow motion of problem-solving ideas", allowing children to consolidate knowledge points and develop thinking habits during the exercises. At the same time, the book contains a large number of life-related case teachings, which integrate the teaching of mental arithmetic skills into specific life scenarios to cultivate children's mathematical thinking and number sense in the real world. The author also uses columns to share some of his unique views on education and social development, which can provide readers with macro-strategic suggestions and guidance. This is a mathematical thinking enlightenment book that is "different" from other educational books on the market. The explanations in this book are lively and interesting, and there are a large number of practical examples related to life to stimulate children's interest and curiosity. The exercises in each chapter are divided into 4 levels according to the difficulty level. Level 4 is the genius level, which is reserved for children who have room for learning to further improve. At the same time, a large number of lifelike picture illustrations allow children with basic reading ability to explore slowly at their own pace, while training logical thinking skills and cultivating interest in mathematics. In addition, this book is not afraid to introduce mathematical language that is higher than the primary school level - algebra, sequence, probability, etc. It uses simple examples as a starting point to guide students step by step to understand these concepts, and then become familiar with and apply them to some problems they may encounter in life.
