数学教学中培养学生估算意识与能力探研

Exploration of the Cultivation of Students' Estimation Consciousness and Ability in Mathematics Teaching

估算教学作为小学数学教学的重要组成部分,具有特别的教学价值和教学特点。在教学中,教师可结合学生学情,贯彻估算意识、形成估算框架,关联学生生活、增强估算技能,指导学生发散思维、提高估算技能,引进数形结合、提高解决问题能力,培养学生的估算意识和估算能力,进一步提高学生数学学科核心素养。

As an important part of primary school mathematics teaching,estimation teaching has special teaching value and teaching characteristics.In teaching,teachers can combine students'learning situation,implement estimation consciousness,form estimation framework,connect students'life,enhance estimation skills,guide students to divergent thinking,consolidate estimation skills,introduce combination of number and shape,improve problem-solving ability,cultivate students'estimation consciousness and ability,and further improve students'core literacy of mathematics.
