在日常生活中,人们在描述一些与数字有关的信息时,往往会使用一些口头语言,如五点三刻,三点一刻……还有我国常用的市制单位,如斤、两,尺、寸,亩……对年份的认识,如2003年,一般读作二零零三年,也是如此。这些现象的出现并不是偶然,更不是对数学读数、写数的认知错误,是一种长期生活经验的积累,是历史文化的传承,是人们在生活中约定俗成的习惯。我们在进行认数、读数教学时,应力求做到以恰当的方式促进学生对读数、写数的正确理解。一、注重数学用语规范的训练根据教材的编排,从低年级开始就对学生进行认数、读数及写数的规范训练,为学生理解四则运算
In everyday life, people often use some verbal language when describing some information related to numbers, such as five and three, three o’clock moment ... as well as the commonly used municipal units in our country such as jin, , Inch, mu ... understanding of the year, such as 2003, generally read as 2003, as well. The emergence of these phenomena is not accidental, nor is it a cognitive mistake in reading mathematics or writing mathematics. It is a kind of accumulation of long-term life experience, the inheritance of history and culture, and the convention of people in life. When we carry out the teaching of reading and counting, we should try our best to promote students’ proper understanding of readings and writing numbers in an appropriate way. First, pay attention to the standardization of mathematical language training According to the textbook layout, from the beginning of the junior high school students to recognize, read and write the number of standardized training for students to understand the four arithmetic
