创设教学情境,可以使学生容易掌握数学知识和技能,更好地体验教学内容中的情感,使原来枯燥的、抽象的数学知识变得生动形象、饶有兴趣。数学情境的创设,是为了更好地为教学服务,应从学生现实生活出发,做适当的理性加工,同时要兼顾学生的年龄特点。因此,情境创设要富有理性。情境教学只有入境,才能生情。那么在小学数学课堂教学中,创设怎样的情境,才能激活思维,增强课堂教学有效性呢? Creating a teaching situation can make it easier for students to master math knowledge and skills, to better experience the emotion in teaching contents, and make the original boring and abstract math knowledge become vivid and interesting. The creation of mathematical situation is to better serve the teaching, should proceed from the real life of students, do the appropriate rational processing, taking into account the age characteristics of students. Therefore, the situation created to be rational. Situational teaching can only be done before entering the country. So in primary school mathematics classroom teaching, create what kind of situation, in order to activate thinking, enhance the effectiveness of classroom teaching?
