当前,不少教师在教学中淡化数量关系,甚至认为不宜出现数量关系,以免学生在解题过程中套用关系,致使解题模式化、机械化,进而抑制学生思维的发展与提升。我认为,数量关系教学不能蜻蜓点水,敬而远之,而应积极面对,因势利导,要让学生在数量关系的建立过程中,体验乐趣,感受魅力,形成思想。下面,我以“每份数×份数=总数”为例,谈谈数量关系教学的几点思考。 At present, many teachers dilute the quantity relationship in teaching, and even think that it is not appropriate to have a quantitative relationship, so as to prevent students from applying the relationship during the process of problem solving so that problem solving can be modeled and mechanized, thereby curbing the development and promotion of students’ thinking. In my opinion, the teaching of quantity relations can not be superficial. At the same time, we should face the situation positively and make the best use of it. Let students experience the fun, feel the charm and form the thought in the process of establishing the quantitative relationship. Now, let’s take “number of copies × number of copies = total number” as an example to talk about the teaching of quantity relations.
