数学是人类长期实践的结晶,因此,在数学教学中,要注重从学生的生活实践经验和已有的知识出发,将学生的现实生活和数学学习紧密结合,为学生提供充分的从事数学活动和交流的的时空,让学生真正体验数学与生活的关系,主动地运用数学观点分析生活现象,从而在自主探索的过程中理解和掌握数学知识,获得解决生活中实际问题的经验。 Mathematics is the crystallization of human’s long-term practice. Therefore, in mathematics teaching, we should pay attention to students ’practical experience and existing knowledge, combine the students’ real life and mathematics study closely, and provide students with sufficient mathematics activities The exchange of time and space, so that students really experience the relationship between mathematics and life, take the initiative to use mathematical point of view of life phenomena, and thus in the process of exploration of self-understanding and mastery of mathematical knowledge, access to practical problems in life experience.
