摘 要:文章以“生活·实践”教育理论为指引，结合小学数学“用字母表示数”的教学价值与核心素养培育需求，构建“教师一小先生一AI智能师”三师协同教学模式。即便该内容后续可能退出小学教材，其在符号意识启蒙、思维方式转型、核心素养奠基中的核心价值仍不可替代。通过聚焦“生活情境融入、实践探究推进、素养落地延伸”三大核心环节，明确三师在教学全流程中的角色分工与协同逻辑，将抽象的符号意识培养转化为生活化、可操作的实践活动，实现“生活即学习”“实践即教学”的教育理念，凸显“用字母表示数”作为素养培育载体的长效价值。

Abstract: Guided by the "Life-Practice" educational theory, this study combines the teaching value of"Using Letters to Represent Numbers" in primary school mathematics with the needs of core literacycultivation to construct a tripartite collaborative teaching model-comprising teachers, "little masters" (peertutors), and AI intelligent tutors. Even if this content may be removed from primary school textbooks in thefuture, its core value in symbol awareness enlightenment, thinking mode transformation, and core literacyfoundation remains irreplaceable. By focusing on three core links-"integrating real-life contexts, advancinginquiry through practice, and extending the implementation of literacy" -the study clarifies the role divisionand collaborative logie of the three tutors throughout the entire teaching process. It transforms the cultivationof abstract symbolic awareness into life-oriented and operable practical activities, realizing the educationalconcepts of "life is learning" and "practice is teaching". This research highlights the long-term value of "Using Letters to Represent Numbers" as a carrier for literacy cultivation, providing a replicable andpromotable practical paradigm for the teaching of core concepts and core literacy culivation in primary schoolmathematics.
