《数学课程标准》指出,“要重视从学生的生活实践和已有的知识中学习数学、理解数学”。因此,数学教学要从学生的生活经验出发,创设学生喜闻乐见的生活情境,让学生通过情境认知、情境体验来获得某种数学知识,进而培养学生的数学学习兴趣,或者通过具体的情境或故事情境,调动学生已有的经验,引导学生将生活经验与数学知识结合起来。那么,如何架起知识与生活的桥梁,使我们的数学课堂焕发活力呢? Mathematical Curriculum Standards states that “Emphasis should be placed on learning mathematics and understanding mathematics from students’ life practice and existing knowledge.” Therefore, the teaching of mathematics should start from the student’s life experience, create the students ’loved and loved life situations, and let the students acquire some kind of mathematical knowledge through situational awareness and situational experience, so as to cultivate students’ interest in maths learning or through specific situations or stories Situation, mobilize the students’ existing experience, guide students to combine life experience with mathematical knowledge. So, how to set up a bridge of knowledge and life, so that our math classroom full of vitality?
