应用题既是小学数学教学中的重点,也是教学中的难点。有不少的应用题,文字叙述比较抽象,数量关系比较复杂,在教学中,我们可采取各种方法帮助学生轻松、愉快的学会复杂关系的应用题,这样既培养了学生的能力,又促进了学生了思维的发展。一、借助于线段图解题,可化抽象的语言到具体、形象、直观图形⒈通过借助线段图解题,可化抽象的语言到具体、形象、直观图形。小学生年龄小,理解能力有限,社会经历少,给理解题意带来较大的困难。教师引导学生用线段图的形式表示题目中的数量关系,更
Applied problem is not only the focus of primary school mathematics teaching, but also teaching difficulties. There are many application problems, the text is more abstract narrative, the number of relations is more complex, in teaching, we can take various ways to help students easily and happily learn the application of complex relationships, so that not only cultivate the ability of students, but also to promote Students develop their thinking. First, with the help of line graphic problem solving, can abstract the language to the specific, image, intuitive graphics ⒈ through the help of line graphic problem, abstract language can be specific, image, intuitive graphics. Pupils are young, have limited understanding and have little social experience, which brings great difficulties to comprehension. Teachers guide students in the form of line segments that the number of topics in the relationship, and more
