一、重视培养儿童两个转化能力在简单应用题教学中,除注意分析数量关系,帮助儿童深刻地理解题意,正确地寻找解题思路外,还应注意培养两个转化能力。一是把应用题的“日常语言”转化为“数学语言”的能力;二是把“数学语言”转化为“数学式子”的能力。理解题意,分析数量关系的过程,实质上就是培养儿童两个转化能力的过程。如教“每个盘里有3个梨,共4盘,一共有多少个梨”?这里应加强直观,引导观察,在明确题意的基础上,深入浅出地分析。首先着重引导儿童明确“要求4盘
First, attach importance to the development of two children's ability to transform In the simple application of teaching, in addition to pay attention to the quantitative relationship, to help children understand the problem, to correctly find the problem solving ideas, but also should pay attention to cultivate two transformation capabilities. One is the ability to translate the ”everyday language“ of the applied question into a ”math language“; the other is the ability to translate ”math language“ into ”math formula.“ The process of understanding the questions and analyzing the quantitative relationship is essentially the process of cultivating two children's transforming ability. Such as teaching ”There are 3 pears in each dish, a total of 4 dishes, a total of how many pear “? Here should strengthen the visual, guide the observation, based on clear questions, in-depth analysis. First of all, focus on guiding children clear ”requires 4 disc
