小学数学人教版六年级下册《第一课比例的意义》教案说课稿
（一）观图激趣、设疑导入 出示课件的第一张幻灯片。师：求比值,完成后,说说求比值的方法,这三个比值是什么关系?18∶12 27∶18 2.4∶1.6生1:用比的前项除以比的后项。生2:这三个比值相等。……【参考答案】 18∶12= 27∶18= 2.4∶1.6= 求比值的方法是用比的前项除以比的后项,这三个比值相等。【设计意图】比和比值是解决比例意义的关键所在,只有唤醒学生已有经验,才能更好地让学生投入到学习比例意义活动中来,为实现教学目标做好铺垫。（二）探究新知师:同学们,每周一的早上我们学校都要举行庄严的升国旗仪式,那么,你们对国旗都有哪些了解呢? 生1:我们的国旗是红色的,上面有五颗黄色的五角星。生2:我们的国旗是长方形的。师:同学们回答得真好,说出了自己对国旗的了解,可以看出同学们对我们国家的热爱,老师希望你们一定要好好学习,为我们的五星红旗增光!五星红旗是庄严而美丽的, 并且它与我们数学也有着密切的联系,这也就是我们今天所要研究的内容——比例。(板书课题:比例的意义)国旗长5米，宽米。国旗长2.4米，宽1.6米。国旗长60厘米，宽40厘米。
小学数学人教版三年级上册《分数的初步认识》说课稿
一、说教材本课内容是人教版义务教育课程标准实验教科书三年级上册90页到91页内容。这部分内容是学生在掌握了万以内整数知识的基础上进行教学的。从整数到分数是数的概念的一次扩展，又是学生认识数的概念的一次质的飞跃。无论是意义，还是读写方法、计算方法，分数和整数都有很大的差异。因此，教材将分数的知识分段教学。本学段是分数的初步认识，这节课是认识几分之一。认识几分之一是本单元教学内容的核心。二、说学情分析在此之前，学生在生活中可能接触过二分之一这样的分数，但并不理解它的含义。分数的产生是从平均分某个不可分的单位开始的，学生生活中已经有这样的经验。例如，妈妈把一个月饼平均分成两份给弟弟和妹妹，每人分得半个月饼。但学生不会用分数来表述。所以,教学中我特别注意从学生已有的生活经验出发，在丰富的操作活动中主动去获取分数的相关知识。
小学数学人教版三年级下册《小数的初步认识》说课稿
一、说教材小数的初步认识是在学生熟练地掌握了分数的基础上进行学习的内容。本课内容包括认识一位小数、两位小数和它的读、写法。认识一位小数和两位小数是小数的初步认识中最基础的知识，学习小数不仅为学生准确清晰地理解小数的含义，也为今后系统地学习小数的知识打下基础。同时，小数的知识在实际生活中应用较广泛，有利于学生运用所学知识技能来解决一些实际的问题。学情分析：小学三年级的学生对小数并不是全然不知，在日常生活中已经有所接触，但由于小数是分数的另一种表现形式，其意义具有一定程度的抽象性，学生要深刻理解小数的意义，还有一定的困难，针对这一现状，教学中应充分考虑学生的生活经验，利用生活与数学知识的契合点，重视直观、引导、注重启发，利用小数与分数之间的联系，让学生亲历小数的形成过程。
