小学数学中,对于单位的换算一直是学生学习的难点,也是老师教学的难点,一方面是因为这方面教学的确很难找到捷径,另一方面是这方面学生概念模糊,缺少生活常识。结合我在小学的多年数学教学经验,我对如何避免学生在单位换算上的易错点和教学对策有自己的看法,并在本文中进行叙述。 Primary school mathematics, for the unit conversion has been a difficult learning for students, but also difficult for teachers to teach, on the one hand because it is indeed difficult to find a shortcut to teaching in this regard, on the other hand is the concept of students in this area fuzzy, lack of common sense of life. Based on my years of experience teaching mathematics in primary schools, I have my own opinion on how to avoid the students’ error-prone points in teaching units and teaching strategies, and describe them in this article.
