在小学低年级数学教学中,数感培养需要创新教学方式,从而有效促进学生数感发展。以往,我们在培养学生的数感时,更多采取数实物的方式。这种方式虽然在小数目的数的认识中有一定的意义,但是对于以间接经验学习为主的大数目数的认识上,价值就不大了。例如,万以内数的认识教学,在数感培养方面要用具体的实物感受一万有多大,显然是有困难的。于是,我们试图借助直接经 In the lower primary mathematics teaching, the number of flu training needs innovative teaching methods, which effectively promote the development of the number of flu students. In the past, when we nurtured the sense of number of students, we adopted more concrete measures. Although this method is of some significance in the understanding of the small number, it is of little value to the understanding of the large number of people who mainly learn from indirect experience. For example, knowing the number of people within a few million is obviously having difficulties in using specific physical experience in terms of number sense training. So, we try to use direct experience
