生活离不开数学,数学离不开生活。数学知识源于生活而最终服务于生活。在教学中要求从学生熟悉的生活世界出发,选择学生身边的事物,提出有关的数学问题,以激发学生的学习动机。数学教学,应从学生已有的知识经验出发,让学生亲身经历参与特定的教学活动,获得一些体验,基于此认识,笔者认为在新教材的教学中,应体现以下几点: Life can not be separated from mathematics, mathematics can not be separated from life. Mathematical knowledge originates from life and ultimately serves life. In teaching, students should be familiar with the world of life from the start, select the students around things, put forward the relevant mathematical problems in order to stimulate student motivation to learn. Mathematics teaching should start from the students’ existing knowledge and experience, let the students experience the participation in specific teaching activities, get some experience, based on this understanding, I believe that in the teaching of new textbooks, should reflect the following:
