人教版新课标小学数学六年级下册用比例知识解决问题说课稿2篇
四、学以致用。1、用比例解决下列问题。五、课后延伸，深化拓展1、万老师骑摩托车从家到学校上班，6分钟行使了480米，照这样计算，他从家到学校共行使了20分钟。他家到学校的距离有多少米？2、今年元旦那天，小丽的妈妈到银川商城购物，发现有件保暖内衣质量不错，于是买了3件，共付了180元。回来后，邻居张大妈也想买几件，于是乘车到银川商城买同样的保暖内衣，她共付了300元，能买几件？3、解决课前提出的问题。（学校旗杆高一般由学校面积大小而定）提醒：同一时间、同一地点的身高和影长成正比例。根据实际情况，可以独立解答，也可以讨论解答。4、实践作业。1、一根粗细均匀的圆木，锯成了5段共用了326分钟，照这样计算，如果把这根圆木 锯成7段，需要多少分钟？2、请同学们利用上一题的原理测一测咱们学校的教学楼的高度。六、课堂总结。说说你的收获。评价自己的表现。教学反思：这节课上完之后我有以下三点感悟：（ 一）课堂永远是无法完全预设的

四、教学流程分析 （一）激趣引入，创设情境 充分利用情境，让学生感受统计的必要性，引导学生体会到解决这类问题的思路是：收集数据、整理数据、做出决策，从而使学生从感性认识上升到理性认识，既培养了解决实际问题的能力，也使学生感到学习扇形统计图的必要性。利用多媒体提供学生感兴趣的生活资料，让学生收集、整理、分析信息，激发学生学习兴趣，体会数学来源于生活。 （二）新旧知识对比，探究学习 教师在设计时，对教材上的例题和有关练习作了修改，从书本指向性非常明确的问题改成了完全开放的问题，有效培养了学生的识图能力，增强了学生思维的开放性。多媒体展示同学们知道的七大洲四大洋的知识并制作成扇形统计图以及书中的例题，引导学生读图思考、小组交流。在此基础上，出示教师收集的扇形统计图资料，引导学生读图交流，并归纳概括扇形统计图的特点和作用，以及在做这样题时应注意的问题。

三、应用知识，解决问题1、练习P63做一做，并根据统计图进行分析和提建议。（1）学生动手制作。（2）用幻灯展示学生作品，并评议。（3）谈自己根据统计图进行分析和提建议2、学生动手绘制折线统计图。（用自己收集的数据进行绘制折线统计图）（1）学生绘制折线统计图。（2）学生谈自己收集数据与绘制折线统计图的目的？（教师选择性地展示学生的作品，并交流）生1：我收集的数据是自己上学期期末考试成绩与这学期第一、二两单元的数学成绩，制图目的是为了清楚地看出自己本学期成绩变化情况。生2：我收集的数据是妈妈店上3月下旬衣服销售情况，目的是为了帮助妈妈如何调整进货。生3：我收集的是今年1—3月份，我家的用电情况，目的是通过观察用电的变化情况来调整用电，尽量做到节约用电。生4：我妈妈是医生，我从妈妈那收集了我7—12岁的身高数据，制折线统计图的目的是为了更好地了解自己的生长情况，并通过这一情况来指导我班同学的饮食。

三、说教学设想课本中以立叔叔从某城市乘火车去北京为情境，我进行了改编，以中秋节来临之际，月饼店进货为主线，通过四个环节进行教学：创设情境，激发兴趣；探索交流，获取新知；巩固强化，内化新知；归纳总结。（一）创设情境，激发兴趣：现在正逢中秋来临之际，因此，以月饼店进货为背景素材，通过课前的谈话，让学生尽快的溶入课堂，并且根据学生喜欢吃月饼的天性，在屏幕上出示大月饼的图片，激发了学生学习的兴趣，随即立刻引入正题，出示表格，让学生寻找数学信息，提出数学问题面对一些以前学过的数学问题，及时的解决，而面对今天需要解决的数学问题，直接让学生列出算式，并通过估算，然后引出课题。（二）自主探索，获取新知：在这个环节中，进行以下四个层次的教学：1、让学生用自己喜欢的方法计算245×12
人教版新课标小学数学三年级下册设计校园说课稿2篇
二、说学情分析：在学生学习了位置与方向、面积等有关知识的基础上，教材安排了“设计校园”的实践活动。通过设计学生熟悉的环境──“校园”的过程，进一步巩固学生已经学习的有关知识，让学生学会应用数学知识解决实际生活中的问题，培养收集、整理、分析信息的意识和能力，以及爱学校的良好情感。教材以重新设计校园为主题，从收集信息、分析信息、设计方案三个方面安排了整个实践活动。三、说学习目标和重难点：1、通过学生自主调查、讨论交流寻找出解决问题的方法，最后设计出自己喜欢的校园。2、让学生更加理解东、西、南、北、东南、西南、东北、西北八个方位，进一步巩固学生已经学习的有关知识。3、让学生学会应用数学知识解决实际生活中的问题，培养收集、整理、分析信息的意识和能力，逐步提高解决问题的能力，以及热爱学校的良好情感。
人教版新课标小学数学三年级下册认识小数说课稿2篇
（一）创设情境，引入新知1、引出小数新课程标准强调数学与现实生活的联系，要求数学教学必须从学生熟悉的生活情景和感兴趣的事物出发，使他们体会到数学就在身边，也感受到数学的趣味和作用，增强学生的数学应用意识。一开始我便与学生谈话：汤老师周末带孩子去超市买东西，可是他看不懂商品的价格，你们愿意帮他吗，(愿意)。大家一起帮他读出这些文具的价格是多少钱。激发了学生的兴趣，让学生充满爱心和自信心走进课堂。然后请学生仔细观察这些价格，有什么不同，从而引出小数的概念。2、教学读法我充分相信学生的能力和知识广度。聪明的学生可能一下子就能读出小数，有的学生家长教过或听到过小数怎样读，所以我让学生大胆试一试，然后经过学生小组讨论总结出小数的读法。
人教版新课标小学数学四年级下册加法结合律说课稿
4、这样的描述太长又难记，让学生想想加法交换律，能用什么简便的方法来表示他们的发现，并自己尝试写一下。提示：用自己喜欢的图形、字母或符号来表示这一规律。板书：(a+b)+c=a+(b+c) 这就是我们今天所学的一个运算定律 (板书：加法结合律)。（三）巩固练习我设计了三个层次的练习，而且形式多样，内容丰富，使全体同学都参与到有趣的数学学习中，又复习巩固了全课的内容。前两题是基础巩固题，是针对加法结合律的定义设计的填空和判断题。三四题是将加法交换律也放入了习题中，通过连线，选择，让学生能够区分加法结合律和加法交换律。五六题则是在刚才的习题上，提出了更高的要求，第五题是让学生自己运用简便方法计算三个数的相加。第六题则是开放题，在一个算式中，给学生两个数，一个空，让学生自己想出一个适合数来使计算简便一些。这样，我就把主动权再次交给学生，充分体现他们的主体性。
人教版新课标小学数学四年级下册小数加减法说课稿
《小数加减法》是人教版四年级数学一个教学内容，本课教材是在学生掌握了小数的意义和性质以及前面非常熟悉的整数加减法的基础上安排学习的，是学生日常生活的需要和进一步学习、研究的需要，理解和掌握小数加减法的算理和算法是小学生基本的而且是必备的数学知识、技能与方法。这一教学内容与老教材相比，突出了计算不在是枯燥乏味，而是选择学生熟悉的感兴趣的素材，作为计算教学的背景。让学生感到计算学习同样是生动、有趣的，使学生在解答用小数计算的实际问题时，理解小数加减法的算理，掌握小数运算的基本方法。再说，小数加减法与整数加减法在算理上是相通的。对于小数加减法，学生有似曾相识的感觉。教材紧紧抓住学生的这一认知特点，有意不给出小数加减法的计算过程，不概括小数的加减法法则，而是刻意引导学生利用已掌握的整数加减法的旧知迁移到小数加减法这一新知中。使学生懂得应用旧知来学习新知是获得知识的一条重要途径。基于以上分析，本课时的教学目标确定如下：
人教版新课标小学数学四年级下册营养午餐说课稿2篇
“营养午餐”是学生既熟悉又陌生的一个课题，熟悉的是学生每天都必须接触，陌生的是学生对于什么样的搭配才是合乎营养标准的“营养午餐”还没有达到科学合理的认识，偏食挑食等不良饮食习惯在学生群体中比比皆是。教材结合学生的生活实际，围绕午餐的营养问题设计了几个数学综合应用活动：首先是民主路小学为学生提供的三种午餐菜谱；其次是营养专家介绍了10岁儿童营养午餐的两个基本指标；接着是让学生尝试合理搭配自己喜欢的午餐菜谱，最后通过统计、排列组合，让学生运用所学知识，解决问题。一方面使学生综合运用简单的排列组合，统计等相关知识解决问题，体会数学在日常生活中的应用价值，增强学生应用数学的意识，另一方面通过了解各份菜中热量、脂肪、蛋白质的含量和营养午餐的一些基本指标，促使学生克服偏食、挑食的毛病，养成科学的饮食习惯。
