人教版新课标小学数学四年级上册因数中间或末尾有0的乘法说课稿2篇
然后我让自主尝试探索末尾有0有乘法，然后让学生自己上台来给大家展示各自的算法，并讨论比较那种算法更简便，从而总结出末尾有0的乘法列竖式的简便方法。为了解决这节课的重点和难点，我在这个环节里又有针对性的设计了两个练习，一个是0和非0的对位，还有一个是积末尾补0。在教学因数中间有0的乘法，因为学生有了前面的基础，所以我直接让学生在两个问题中选择一个解决。重点强调了因数中间0不能漏乘。在练习方面，我设计了看谁的眼睛亮，通过找错误，学生练习时，老师观察到有共性的的错误，通过视频展示台，让学生来寻找错误，再次突破本课的重点。一题是360×25因数末数一共有一个0，而积的末尾应该有三个0。让学生进行讨论，再一次让学生体会了积末尾0个数确定的方法。在巩固和拓展联系环节，设计了闯关游戏，先是基本的计算练习，接着是因数末尾0个数的判断和解决问题的联系，通过练习，巩固竖式的简便写法，提高学生的计算能力。
