人教版新课标小学数学五年级下册整数加法的运算定律推广到分数加法说课稿
（一）教学内容：我说课的内容是第5单元中内容，（二）教材地位：加法是数学中最基本的运算之一。从教材的纵向联系来看，几年前已学过整数加法和小数加法，以及加法的运算定律，知道它不仅适用于整数加法，而且也适用于小数加法。那么是否也适用于现在所学习的分数加法呢？这就是我们这节课要研究的问题，当然，结果是肯定的。通过本课的学习，将整数加法的运算定律推广到分数加法，可使学生对加法的认识从感性上升到理性。为后面学习分数加法的简便计算打好基础，同时也为学习小数、分数混合运算奠定基础。其次，将整数加法的运算定律推广到分数加法，也拓展了加法运算定律的使用范围，丰富其内涵。而且加法运算定律字母表示形式，为以后代数知识的学习奠定了初步基础。
人教版新课标小学数学五年级下册假分数化成整数或带分数说课稿2篇
一、说教材（一）教材简析《假分数化成整数或带分数》是小学数学五年级（下册）第六单元中的内容。本节内容安排了两个例题。这部分内容是在学生掌握了假分数的意义后，进一步学习把假分数化成整数或带分数，有利于以后进行分数计算打下坚实的基础。（二）教学目标根据教材编排特点，我确定以下教学目标：1、知道带分数是假分数，是整数与真分数合成的数。2、会把假分数化成整数或带分数。3、使学生经历假分数化成整数或带分数的探索过程，进一步发展数感。4、培养良好的学习习惯，树立学好数学的信心。（三）教学重、难点会把假分数化成整数或带分数。二、说教法、学法通过这一环节的教学，把假分数化成整数或带分数时，先要让学生根据假分数的含义进行思考。在这个基础上，再启发学生根据分数与除法的关系计算出结果，并把用不同方法求得的结果进行比较，认识到每种方法都是有道理的。
