摘 要
随着教育改革的深入推进，数学核心素养的培养日益受到关注，而估算能力作为数学思维的重要组成部分，在实际问题解决中具有不可替代的作用本研究以小学数学教学为背景，聚焦学生估算能力的培养，旨在探索有效的教学策略和方法通过文献分析、问卷调查及课堂观察等多维度研究方法，系统梳理了当前小学数学教学中估算能力培养的现状与不足，并结合具体案例设计了一系列针对性的教学活动研究发现，传统教学中对估算重视不足，学生缺乏实践机会和方法指导，导致其估算意识薄弱。
关键词：数学核心素养；估算能力；教学策略
Abstract：With the deepening of the educational reform, The cultivation of mathematical core literacy is getting increasing attention, And estimation ability, as an important part of mathematical thinking, This study is based on primary school mathematics teaching, Focusing on the cultivation of students' estimation ability, It aims to explore effective teaching strategies and methods through literature analysis, questionnaire survey and classroom observation and other multi-dimensional research methods, Systematically sort out the current situation and deficiency of the estimation ability cultivation in the current primary school mathematics teaching, Combined with specific cases to design a series of targeted teaching activities research findings, Insufficient emphasis on estimation in traditional teaching, Students' lack of practical opportunities and methodological guidance, Lead to its weak awareness of estimation.
Key words：Mathematical Core Literacy; Estimation Ability; Teaching Strategy
