一、注重数学概念的生活性教学数学概念的生活性教学,就是要将教学的数学概念与学生的实际生活紧密地联系起来,充分体现数学知识来源于生活的理念。学生不仅对身边环境中事物蕴含的数学知识具有强烈的好奇心,而且还对那些事物具有极强的亲切感。如在教学“正数”与“负数”的概念时我是这样做的:举出身边事例——六(2)班学生李刚向东走了8米,又回头向西走了5米,那么他最后 First, pay attention to the concept of life-based mathematics teaching concept of life-based teaching of mathematics, is to teach the concept of mathematics and student life closely linked to fully reflect the mathematical knowledge derived from the concept of life. Students not only have a strong curiosity about the mathematical knowledge contained in the surroundings, but also have a strong sense of intimacy about those things. As in the teaching of the concept of “positive” and “negative” I did the following: citing examples around - Li Gang, a six (2) class student, walked 8 meters eastward and turned west again 5 meters, then he last
