“Early childhood education is the most critical stage of learning; a poor early start will have lasting effects on later development. In my own personal experience, I have found that students often have the most trouble with mathematics. It is truly a shame that many students often give up on math due to falsely perceived difficulty. Teacher Huang's innovative new work, 123 Easy Teaching, is the result of many years of teaching experience. This book series addresses the needs of youth education and eliminates the difficulties and bottlenecks frequently encountered during the elementary learning process. This allows children to gain confidence in their mathematic abilities, furthermore, it allows them to learn happily without struggle. These books are vital to providing a solid arithmetic foundation for children.”
Zhang Huatang, President of Hukou Senior High School
