估算教学是小学数学教学中重要的一部分。学生的估算能力反映了学生对数学运算方法的理解水平和熟练程度。教师培养和提高学生的数学估算能力,有利于训练学生良好的口算和心算能力,增强学生的数学反应能力,提高学生的数学运用能力。本文主要研究如何更好地推进小学数学教学中的估算教学,通过根据教学内容设计估算问题、将估算与其他计算方法相结合、将估算教学与生活场景相联系三方面展开有关论述。
Estimation teaching is an important part of elementary mathematics teaching. Students ’ability to estimate reflects students’ level of understanding and proficiency in mathematical methods. Teachers training and improving students ’ability to math estimation help to train students’ good oral and mental arithmetic ability, enhance students ’ability of math reaction and improve students’ mathematical ability. This article mainly studies how to advance the estimation teaching in the elementary mathematics teaching. Through the design of the estimation problem according to the teaching content, the estimation is combined with other calculation methods, and the discussion about the relationship between the estimation teaching and the life scene is discussed.
