数学思想是学生数学学习的灵魂,对学生的数学学习起着重要的指导作用,因此,在小学数学课堂教学中应该渗透数学思想。我在执教人教版六年级上册鸡兔同笼这节内容时,通过学生交流解决鸡兔同笼问题的方法和过程,有以下几点感悟。一、把原题里的数字改小,渗透“化繁为简”的数学思想《孙子算经》中原题的题意是:笼子里有若干只鸡和兔。从上面数,有35个头,从下面数,有94只脚。鸡和兔各有几只?改写后的题目是:笼子里有若干只鸡和兔。从上面数,有8个头,从下面数,有26只脚。鸡和兔各有几只?通过改小数字,使题意变得简单,
Mathematical thinking is the soul of students 'mathematical learning, which plays an important guiding role in students' mathematical study. Therefore, it is necessary to infiltrate the idea of mathematics in elementary mathematics classroom teaching. When I was teaching the sixth grade of the PEP, I learned the following methods and processes to solve the problem of chicken and rabbit in the same cage through the exchange of students. First, the number of the original title to small, infiltration “mashup to Jane ” mathematical thinking “The grandson sums up” the title of the original question is: there are a number of chickens and rabbits in the cage. From the top, there are 35 heads, from the bottom, there are 94 legs. There are a few chickens and rabbits? After rewriting the title is: There are several chickens and rabbits in the cage. Number from the top, there are 8 heads, from the bottom, there are 26 feet. How many chickens and rabbits? By changing the number of small, so that the problem becomes simple,
