Review 小数点的移动说课稿 根据教学内容和教学设计意图、设计思路～现对小数点的移动这一课时作说课如下: 一、 教学内容 小数点位置移动引起小数大小的变化是小数的又一性质。它与前面讲的小数的性质不同在于～小数点的移动主要是研究小数点移动如何改变小数的大小。不仅是小数乘法的计算依据～也是单名数和复名数相互改写的重要基础。通过这部分内容的学习还有助于学生用联系变化的观点认识事物。在学习本节内容时学生已经对小数有了一个明确的认识～认识了解了小数各部分的名称～学会了比较小数的大小～掌握了小数的基本性质以及单名数之间的改写。 二、 教学目标 根据教学大纲、教学内容的要求～结合本班学生的实际情况我拟定了如下教学目标。 1、 知识与技能 ,1, 理解并掌握小数点位置移动引起小数大小变化的规律。 ,2, 会应用小数点移动引起小数大小变化规律进行计算～解决实际问 题。 2、 过程与方法 通过复习旧知、引入新课～学生自主探究、小组合作的形式共同归纳 总结 初级经济法重点总结下载党员个人总结TXt高中句型全总结.doc高中句型全总结.doc理论力学知识点总结pdf 小数点移动引起小数大小变化规律的过程～培养学生正确的学习方法。 cense.
