笔者多年从事小学高年级数学教学工作,特别是今年来随着教材的不断改革,针对小学六年级数学十一册重点内容的解题思路进行了反复研究。现将点滴体会摘录如下:一、分数乘、除法应用题的解题思路探讨学生在解答“分数乘、除法应用题”时,找准单位“1”尤其重要,比和被比的量是关键所在。只有分清量于量的关系,才能正确地解答此类应用题。
I have been engaged in the teaching of mathematics in the upper grades of primary school for many years. In particular, with the continuous reform of teaching materials this year, I conducted repeated research on the solutions to the key issues of mathematics in the sixth grade of primary school. Now excerpts will be excerpted as follows: First, the fractional multiplication, division of the problem-solving ideas to explore the application of the students in the answer “fractional multiplication, division of the application of question ”, to identify the unit “1 ” is particularly important, The amount is the key. Only a clear relationship between quantity, in order to correctly answer such applications.
