小学数学人教版一年级上册《8和9的认识》说课稿第二课时
一、教材分析义务教育课程标准实验教科书数学（人教版）一年级上册第五单元，把8和9的认识放在同一节课中完成，编排与前面6和7的认识基本上一样，只是要求更高。教材中提供给学生数数的资源虽不如6和7明显，却更丰富。提供给学生数数的对象是以“热爱自然，保护环境”为主题的生动画面，其内容有人、花、树、花盆、蝴蝶、黑板上的字等。画面除数数外，还体现了环保教育的主题。8和9的序数意义仍是采取6和7的编排方法，不同的是让学生更具体地感受几和第几的意义的不同。基于以上分析，确定了以下教学目标：1．体会8和9的基数的含义。 2．了解8和9在自然数中的排列顺序，会比较0～9各数的大小，知道8和9的序数含义。 3．培养学生初步的收集信息、处理信息的能力。 4．结合8和9的学习，向学生渗透环保教育和劳动教育。 教学重点、难点：学会比较0—9各数的大小。

小学数学人教版一年级上册《0的认识》说课稿第二课时
尊敬的各位老师：大家好！我说课的内容是九年义务教育教科书［人教版］一年级数学上册三单元第七节《0的认识》。下面我从教材、学生、教法、学法、教学过程、板书、课后反思等几个方面谈谈对本节课的理解和设计。 一、说教材 1、教材简析： 日常生活中经常使用0，在不同场合，0往往有不同的意思。对此，教材有明确的要求。 （1）、着重教学“一个也没有，可以用0表示”。让学生在情景中体会0也是一个数，它的产生也是计数的需要。 （2）、结合直尺教学0，0还可以表示起点。 （3）、让学生体会0在生活中的广泛应用。 教材通过猴子吃桃的有趣情境引入，使学生直观体会到什么都没有可以用“0”来表示。接着利用直尺认识“0”还可以表示起点，并使学生进一步熟悉了数的顺序。在学习了“0”的书写后，利用小鸟等动物活动图学习有关“0”的加减法，使学生感受生活中的数学，快乐学习。 2、学习目标： 这节课我和学生要达到的学习目标是： （1）、通过观察感知,让学生知道0可以表示“没有”，还可以表示“起点”，并且会给数排列顺序。
小学数学人教版六年级下册《第二课成反比例的量》教案说课稿
【教学过程】（一）观图激趣、设疑导入 出示课件的第一张幻灯片。1、成正比例的量有什么特征?2、正比例关系式。生1：两种相关联的量,一种量变化,另一种量也随着变化。生2：两种量中相对应的两个量的比值（商）一定。生3：=k(一定)。师:同学们非常棒！我们今天继续学习两种量的另外一种关系。 (板书:成反比例的量)【设计意图】这种方法的导入，简简单单的一道练习题,把学生的注意力吸引到本节主要内容上来,激起学生的好奇心,真的还有另外一种关系!我可得好好听一听。这样在学习反比例时学生会始终保持高度的精神集中,有利于教师教学顺利进行。（二）探究新知教学例2,探究反比例的意义,理解成反比例的量。1、出示PPT课件回答问题。杯子的底面积与水的高度的变化情况如下表。 杯子的底面积/cm²1015203060…水的高度/cm302015105…观察上表,回答下面的问题。（1）表中有哪两种量?（2）水的高度是怎样随着杯子底面积的大小变化而变化的?（3）相对应的杯子的底面积与水的高度的乘积分别是多少?生1:表中有杯子的底面积和水的高度这两种量。生2:从表中可以看出:水的高度随着杯子的底面积的变大而不断变小,这两种量是相关联的两种量。生3:我来回答(3),相对应的杯子的底面积与水的高度的乘积分别是:10×30=15×20=20×15=30×10=60×5=…=300。生4:乘积一定。师:底面积与高的乘积表示的是什么?生:水的体积。(板书)师：你会算出水的体积吗？生：会。（学生计算，教师出示课件订正）2、揭示反比例的意义。师:积是300,实际就是倒入杯子的水的体积。同学们能用式子表示出它们的关系吗?生:它们的关系是:底面积×高=体积。师:同学们,我们用概括正比例意义时的方法来概括一下反比例的意义吧!生:像这样,两种相关联的量,一种量变化,另一种量也随着变化,如果这两种量中相对应的两个数的乘积一定,这两种量就叫做成反比例的量,它们的关系叫做反比例关系。(板书反比例的意义)3、用字母表示反比例关系:xy=k(一定)。(板书)4、牛刀小试。锅炉房烧煤的天数与每天烧煤的吨数如下表: 每天烧煤的吨数/吨11.522.53烧煤的天数/天3020151210(1)表中有哪两种量?它们是不是相关联的量?(2)写出几组这两种量中相对应的两个数的积,并比较大小,说一说这个积表示什么。(3)烧煤的天数与每天烧煤的吨数成反比例吗?为什么?【参考答案】 (1)每天烧煤的吨数和烧煤的天数,是相关联的量。 (2)1×30=30 1.5×20=30 2×15=30 2.5×12=30 3×10=30 积相等,这个积表示这批煤的总吨数。 (3)成反比例,因为烧煤的天数与每天烧煤的吨数的积一定。【设计意图】学生通过观察、发现、概括经历了整个学习过程,逐步形成定向思维方式,为学会学习打好基础。
小学数学人教版六年级下册《第二课比例的基本性质》教案说课稿
（一）观图激趣、设疑导入 师:上一节我们已经认识了比例,知道两个比怎样才能组成比例,下面请同学们判断一下下面各组的比能否组成比例。(1)0.4∶和1.2∶2 (2)和生1:根据比例的意义,第(1)题,这两个比的比值相等,都是0.6,所以(1)题的两个比能组成比例。生2:我来回答第(2)题,我也利用比例的意义,求出=5,=6,这两个比的比值不相等,所以第(2)题的两个比不能组成比例。师:这两名同学回答的真好,有理有据,让我们为他们的表现鼓掌!师:今天这节课,我们将共同来学习用另一种方法来判断两个比能否组成比例,同学们想知道是什么方法吗?生:想知道。师:那就是比例的基本性质(板书课题:比例的基本性质)。【设计意图】复习学生已有的知识,唤醒学生已有学习经验,教师的提问吸引了学生的注意力,也引发学生的好奇心,为学习新知识开了一个好头。
