小学数学中有许多内容既有联系又有区别,为了防止学生学习知识的混淆,苏教版数学教材中安排了很多比一比的环节,旨在让我们引导学生通过比较突出教学重点,突破教学难点,使学生容易接受新知识,提高辨别能力,从而扎实地掌握数学知识,发展逻辑思维能力。特别是在计算教学方面,比较的应用更是频繁,发挥的作用也不可替代,仅低年级的计算教学中就有加减法的比较、乘除法的 There are many elements in primary school mathematics both connected and different, in order to prevent students from learning the confusion of knowledge, the Sujiao version of mathematics textbooks arranged a lot more than one aspect, designed to allow us to guide students through a more focused teaching, breakthrough teaching Difficulties make it easy for students to accept new knowledge and improve their ability to distinguish so that they can master mathematical knowledge and develop their logical thinking ability. Especially in the calculation of teaching, the more frequent applications, the role played can not be replaced, only in the lower grades of teaching there is a comparison of addition and subtraction, multiplication and division
