“小数除法”是整数、小数、分数、百分数四则运算中的重要组成部分,现实中需要运用“小数除法”计算的实际问题很多,通过这一内容的学习,可以提高学生的计算能力,同时发展学生的数学思维。一、探索计算方法1.引导学生自主探索。结合具体情境,充分利用学生的生活经验和已有知识,引导学生自主探索小数除法的计算方法。教师要联系数的意义进行算理指导,利用情境支撑算理理解,让学生掌握小数除法计算方法,依据 “Decimal division ” is an integral part of the integer, decimal, fractional, percentage of the four operations, the actual need to use “decimal division ” calculation of many practical problems, through the learning of this content, you can improve students’ calculations Ability to develop students’ mathematical thinking at the same time. First, explore the calculation method 1. Guide students to explore. Combining with specific situations, students should make full use of their life experience and existing knowledge to guide students to independently explore the calculation of fractional division. Teachers should associate the meaning of the number of arithmetic guidance, the use of context support mathematical understanding, so that students master the decimal division method of calculation, based on
