估算是一项重要的数学计算能力,与数感的形成、知识的应用有十分密切的联系。许多国家都非常重视学生估算能力的培养,我国也不例外。《数学课程标准》对估算教学提出新要求,注重估算意义的理解,强调估算要联系生活实际,体现估算在生活中的作用。在小学估算教学实践中,学生的估算意识淡薄,不能灵活运用估算解决问题。鉴于此,笔者认为在小学数学教学中有必要优化估算教学,培养学生的数学素养。当前小学数学估算教学存在的突出问题
Estimation is an important mathematical calculation ability, which is closely related to the formation of sense of number and the application of knowledge. Many countries attach great importance to the training of students’ estimation ability, and our country is no exception. The Mathematics Curriculum Standard puts forward new requirements for the teaching of estimation, emphasizes the understanding of the significance of the estimation, emphasizes that the estimation should relate to the actual situation of life and reflect the role of estimation in life. In the teaching of primary school estimation, students’ sense of estimation is weak, and they can not flexibly use the estimation to solve the problem. In view of this, I believe that it is necessary to optimize the estimation of teaching in mathematics teaching in primary schools to develop students’ mathematical literacy. The prominent problems in current mathematics estimation teaching in primary schools
