低年级的应用题虽然简单,却是教学中的难点。学生在选择解题方法时,往往只注意题目是一个因素,常常把运算与个别词语联系起来,如见到“还剩”、“少”就用减法,看到“一共”、“多”就用加法,这直接影响学生对应用题数量关系的理解,影响学生解答复合应用题的能力。因此选择恰当的方法进行应用题教学是十分重要的。比较是数学思维的重要方法,也是小学数学教学中常用的一种逻辑方法。“比较是一切理解和概括的基础。”引导学生对应用题进行观察,并从不同的角度去比较,让学生在感知的基础上,通过比较思考,进
Although the application of the low grade is simple, but it is difficult in teaching. Students in the choice of problem-solving methods, often only pay attention to the problem is a factor, often associated with the operation of individual terms, such as to see the “remaining”, “less” subtraction, see “,” More “is added, which directly affects students ’understanding of the relationship between the number of application questions, affecting students’ ability to answer compound application questions. Therefore, it is very important to choose the appropriate method to apply the teaching of the problem. Comparison is an important way of thinking in mathematics, but also a kind of logical method commonly used in elementary mathematics teaching. ”Comparison is the basis for all understanding and generalization. " Guide students to observe the application of the problem, and from different perspectives to compare, so that students on the basis of perception, through more thinking, into
