韩冬梅小数的性质教学设计

韩冬梅小数的性质教学设计 小数的性质 临江市大栗子街道南楼小学:韩冬梅 教材分析: 小数的性质是小数四则计算的基础。根据小数的性质～可以化简小数～也可以不改变小数的大小～在小数末尾添上一个或几个“0”～或者把整数改写成小数的形式。教学时～要通过比较、辨析、抽象、概括等一系列的思维活动～帮助学生理解和掌握小数的性质。 学情分析: 本班共有学生13人～男生6人～女生7 人。从去年的学习成绩看～该班大部分学生平时在数学学习上态度较好～上课能认真听讲～平时能自觉按时完成作业～数学成绩一直很稳定。个别学生基础较差～存在计算不准确、理解分析能力差等现象。 教学理念: 数学课程 标准 excel标准偏差excel标准偏差函数exl标准差函数国标检验抽样标准表免费下载红头文件格式标准下载 指出～数学教学活动必须建立在学生的认知发展水平和已有的知识经验基础之上。教师应激发学生的学习积极性～帮助他们在自主探索和合作交流的过程中真正理解和掌握基本的数学知识与技能、数学思想和方法。基于这样的教学理念～在设计本节课时～我努力从现实生活中寻找数学的素材～引导学生进行观察、比较、猜想、用各种方法验证,应用小数的意义～用赋以单位名称的方法～进行名数转化～再加以比较～从而得出结论,也可通过画图法来论证,。在多种方法论证的扩展中突破难点～使学生认同最后结论。 教学目标: obstacles, correcting misunderstandings, advocate good cadre style. 2, adhere to the scientific decision-making and democratic decision-making decision-making law.
