小学生认知以直观为主,在数学教学中若单以语言直观方式进行讲解,学生不易理解,而借助情境,以学生所熟悉的、形象的场景帮助学生认知、理解,更利于学生掌握知识。在小学数学教学中,情境在不同的环节有不同的作用,导入环节的情境有利于激发学生兴趣,探究环节的情境有利于学生对知识的理解,练习环节的情境则利于学生应用知识。对此,文章将结合数学教学实践对不同环节情境创设作简单分析。一、导入情境,激发学生兴趣 The pupils’ cognition is mainly intuition. If the students are not easy to understand in the teaching of mathematics, they are not easy to understand. With the aid of the situation, students are familiar with the image of the scene to help students understand and understand, but also conducive to students to master knowledge . In elementary mathematics teaching, situations have different roles in different aspects. Situations in which they are introduced are conducive to stimulating students ’interest, and situations in inquiries are beneficial to students’ understanding of knowledge. Practice situations help students to apply knowledge. In this regard, the article will be combined with mathematical teaching practice to create a simple analysis of different aspects of the situation. First, the introduction of the situation, to stimulate student interest
