数学课程标准指出:要从学生已有的生活经验出发,让学生亲身经历将现实问题抽象成数学模型并进行解释与应用的过程,进而使学生获得数学理解的同时,在思维能力、情感态度与价值观等多方面得到进步与发展。教学实践表明:学生学习的内容和学生熟悉的生活背景越贴近,学生自觉接纳知识的程度就越高。所以,我们应从学生熟悉的生活情境出发,在学生已有的知识经验的基础上,有意识地创设宽松、自然的生活情境,使学生在潜移
According to the standard of mathematics curriculum, it is necessary to start from the students' existing life experiences and let the students experience the process of abstracting the practical problems into mathematical models and explaining and applying them in order to enable students to acquire mathematical understanding, Values and many other aspects of progress and development. The teaching practice shows that the closer the student learning content and the students' familiar life background are, the higher the students consciously admit the knowledge. Therefore, we should start from students 'familiar life situations and consciously create relaxed and natural life situations based on the students' existing knowledge and experience so that students will gradually migrate
