人教版新课标小学数学一年级上册连加 说课稿
[设计意图：心理学研究表明低年级学生注意力集中时间较短，兴趣容易转移，针对这一特点，出示学生情有独钟的小动物，增加情趣性，充分激发学生的兴趣，形成探究的欲望。这种疑惑，正蕴含着不解、猜度以及思维的发动；这惊奇，则蕴含着求索、发现以及对思维的刺激。至于哪种积极的探究欲望，可使学生获得想象力和猜度的乐趣，维系发现和创造的信心。通过讲讲练练，既抓住了重点，又突破了难点。]4、回忆总结，系统建构请学生回答做连加时该提醒小朋友注意什么？最后师生共同小结。[设计意图：培养了学生口头表达能力，便于教师及时掌握情况，收取反馈信息，加深理解。促进学生的思维由具体形象逐步向抽象的逻辑思维过渡。]（三）巩固强化，拓展思维1、基本题：（1）集体练习，摆一摆再填数，通过操作学具，巩固连加知识。（2）看图列连加算式计算。
人教版新课标小学数学四年级上册梯形说课稿
1、找一找出示七巧板图，设疑：图中你能找出几个梯形？这个梯子最多能达到多高的高度？（见课件）2、拼一拼：①利用两个完全一样的梯形，拼出一种你熟悉的图形。②利用多种梯形图片，摆出一种最喜欢的图案。创设问题情境，深化思维层次，构建知识体系1、通过活动，培养学生创新意识和审美情趣，充分体现“玩中学，学中玩”的新课程理念。2、教会学生在活动中运用新知、拓展思维、加深认识，增强了学生的参与意识和主体意识。3、在拼摆中渗透转化思想，为梯形的面积推导作铺垫，构建新知学习的立体框架。五、交流评价，总结升华1、小结全课：谈谈你的收获及感想。2、集体评价：自评、互评自己在本课中的表现。完善知识结构，训练思维品质，升华发现能力①通过人性化语言，体现以人为本思想。②引入互动评价方法，交流活动感受，形成自我反馈机制。

（教师要深入各个小组中，参与学生方案的制定，但教师不是决策者，决策权在学生手中。）【设计意图：练习设计围绕本节课的教学目标，具有层次性。同时，开放性练习的设计——采用小组合作，让学生设计购书方案，使学生进一步感受到生活中处处有数学，运用数学知识还能省钱，合理安排日常生活开支，培养了学生自觉应用数学的意识。】五、课堂总结。同学们，通过这节课的学习，你有什么感想？你们今天的表现都很出色。其实生活中还有许多问题需要我们用数学知识去发现、去思考、去探索，希望大家能做个有心人！教学设计自我评析：新课程标准指出：“数学源于生活、寓于生活、用于生活。教师应重视从学生的生活经验和以有的知识中学习数学和理解数学。”

（二）合作交流，探究新知出示例题。（小黑板）先全班同学读题，教师在解释说明题目中“存定期一年”表示什么意思。一般来说，存款主要分为定期、活期等储蓄方式。所谓活期存款是指储户可以随时提取的一种方式；定期存款是有一定期限的一种存款方式，定期存款又分为整存整取和零存整取等形式。现在银行的定期存款有三个月、六个月、一年、二年、三年、五年的等等。（让学生在议一议、说一说的基础上，说出自己是怎样想的，交流归纳对问题的认识，理解存款的定期、活期的年月限即时间，以及存款方式。）小丽存的是“定期一年”，即小丽在银行存的100元在一般情况下要在银行存一年，如果有特殊情况也可以提前提取。下面请同学们合作交流，思考如下几个问题。（出示投影片。）（1）你猜一猜，小丽把100元存入银行叫做什么？（本金）（2）你估算一下，小丽把100元存入银行，定期一年，全部取出，取出的钱会大于100元吗？为什么？

得到13－8=这个算式后，我让小朋友们想办法，“13－8怎么算？你是怎样想的？把你的想法告诉你小组的同学们。”由于我是用讲故事的形式引出这一问题的，因此在计算13－8时，小朋友们就被迫要自己想办法去计算，而不能光借助情境图去直接数出得数。这并不阻碍算法的多样化，相反更好地实现了算法多样化的目的，真正让学生成为了数学学习的主人。为了增加这堂课的趣味性，我有意将学生说出来的各种算法分别以他们的名字来命名，这样一来，学生兴趣盎然，都积极投入到了寻找算法的思考活动中来了。在寻求多样化的过程中，充分发挥了学生学习的主体性，培养了学生的创新精神，让每一个学生都能体验学习的成功。学生们在思考、讨论中可能会出现这样几种算法：

2，解决三个圆片能摆出的数。小精灵聪聪也给大家提问题了：（课件出示：你能用三个圆片表示不同的数吗？）你们回答他，能不能？（1）现在请小朋友们自己动手摆一摆，并且不自己摆出来的数写在老师发给你们的纸上，看谁摆的又快又对。（2）汇报结果：你摆了几个数？分别是什么？是怎么摆的 ？这个活动的设计是为了培养学生的动手操作能力，提高学生学习数学的热情。利用自己总结出来的方法来进行操作，让学生体会到成就感。通过学生的汇报，培养学生的语言表达能力，让学生的手，脑，口的能力同时得到了锻炼。3，小朋友们真棒，现在我们不摆圆片，你能不能在脑子里想着摆圆片的方法，在纸上写出四个圆片都能表示那些数字呢 ？这个活动的设计，是让学生从操作走向有序的思维，让学生有条理的思考问题，将数学抽象化。
人教版新课标小学数学四年级下册连减的简便运算说课稿
在运用定律进行简便计算时，学生仍然出现这样那样的错误，这一点我们在备课中应有所意识，适当调整课时安排，并充分考虑学生练习中可能出现的错误，加强易混知识的辨析练习。 四、教学目标:1、认识目标：使学生理解并掌握从一个数里连续减去两个数的几种常用算法，并能根据具体情况选择合适的方法进行简便计算。2、能力目标：培养学生根据实际情况灵活选择算法进行计算的意识与能力，提高学生观察比较能力和思维的灵活性，发展学生思维。 3、情感态度价值观目标：通过学习活动，激发学生的学习兴趣，使学生感受到数学与现实生活的联系，学会用所学知识解决简单的实际问题。 五、教学重点： 理解并掌握从一个数里连续减去两个数的几种常用算法，并运用其进行一些简便计算。
人教版新课标小学数学一年级下册多些、少些、多得多、少得多说课稿
在100以内数的范围里，18比50是少得多，但到了万以内数的范围内，可能只是少一些，所以结合具体情境帮助孩子体会是很重要的教学方法。想想做做第1题是小孩在进行拍皮球比赛，让孩子选合适的答案，在小组中说说是怎么想的，孩子在交流中就能体会到12比46少得多，50比46多一些，85比46多得多；想想做做第2题是发生在校园里的一个场景，让孩子自己选合适的答案，说说怎么想的，孩子就能体会到16比38少的多，36比38少一些，40比38多一些；第3题的场景是在商店里，让孩子先讨论、认识“贵多啦”的含义，在进行选择，在选择、辨析时进一步明白贵多啦就是“用的钱多得多”；最后，和孩子进行一些活动，比比身高（孩子和孩子比、老师和孩子比）、比比身边的一些数量大小，让孩子尝试用语言描述的同时体会数量之间的大小关系，感受到数学就在身边。最后由一个游戏结束本节课，让孩子拿一个数同45比一比，自己想两个数让同桌比一比，练习使用多些、少些多的多、少的多描述两个数量之间的大小关系，增强合作能力。
人教版新课标小学数学一年级下册十几减9 说课稿3篇
2．通过动手操作、交流算法，使学生经历十几减9的过程，知道想加算减、破十法、连减等多种计算方法，理解算理，掌握算法。能正确计算。3．在学习过程中，培养学生简单的推理能力、表达能力和解决问题的能力。教学重点：掌握十几减九的计算方法，正确、熟练的进行计算。教学难点：经历十几减九的过程，感受算法多样化，理解算理。我的教学过程分为四个大环节，其中第二环节是本节课的重点环节，我又设计了五个小层次：下面我就具体说一说我的教学过程。一、创设情境，复习导入（3分钟）我以元旦快到了，班里要举行游艺活动这样的情境进入练习。【设计意图：在带着学生走向新知之前，再现与新知有关的原认知，复习前面所学的20以内的进位加，数的分解和组成及10减几等知识，为今天学习新课做好铺垫。】接着我以元旦游艺活动，班里要用气球布置教室来引入新课。【设计意图：以学生感兴趣的身边问题吸引他们的注意力，激发兴趣，并巧妙引出新课。】
人教版新课标小学数学一年级下册整十数加、减整十数 说课稿4篇
2、教材分析整十数加、减整十数的计算是在10以内加、减法的基础上进行的，只是计数单位不同，这里以十为计数单位。教学内容的编排，分三个层次：一、以实际情景——花卉展提供计算题，并呈现算法的多样化；二、让学生动手操作（如摆小棒）理解算理、掌握算法；三、脱离直观手段，让学生思考算法。通过让学生在生动具体的情境中学习计算，引导学生独立思考与合作交流多种不同的算法，进一步培养计算能力。这样安排，有助于学生加深对相同单位的数可以直接相加、减的认识，为后面学习任意两个数相加、减打基础。整十数加、减整十数属于计算教学中的重点内容之一，应给予足够的重视。教材的编排是由直观操作等依靠实物思考到脱离实物思考，遵循由具体到抽象的原则，有利于学生抽象思维的培养，为进一步提高计算速度、培养计算能力，解决实际问题打基础。
人教版新课标小学数学三年级下册用连乘解决问题说课稿2篇
3、小结比较观察三种方法，提出问题：为什么同一个问题有三种不同的解决方法？学生交流，教师小结：先解决的问题不同，选择的信息不同，图形拼摆的不同，解决的方法就不同，体现数形结合的思想。相同点是：无论思路如何，都是用连乘的方法解决问题。板书课题：解决问题——两步连乘应用题生活中还有很多这样的清况，想不想再尝试一下。（三）联系生活，优化方法，拓展深化，学校有特异为这些参加比赛的同学们购买了矿泉水，出示画面：共有20箱矿泉水，每箱24瓶，每瓶2元，请问学校共要支付多少钱？学生独立完成观察和思考的角度不同，先后选择的信息不同，所以同一道题有不同的解决方法。看来大家多用连乘的方法解决问题有了进一步的理解。生活中类似这样的问题很多，再来看一看：学校定好了水，付了钱，总得运回来吧.出示搬运车搬水到卡车上的画面：搬运车一次搬4摞，一摞3箱，一箱24瓶，请问搬运车一次能搬多少瓶？
人教版新课标小学数学三年级下册整十、整百数乘整十数说课稿
一、说教材与学生本节课所授内容是人民教育出版社出版的，义务教育课程标准实验教科书，小学数学三年级下册第五单元《整十、整百数乘整十数》。《整十、整百数乘整十数》这一知识点经常用来解决我们在日常生活中遇到问题，为发展学生灵活运用不同计算策略解决问题的能力打下基础。同时体现新课标提出的“人人都能获得必要的数学”这一理念。本册教材是在学生能够比较熟练地口算整十、整百数乘一位数的基础上进行教学的。口算是笔算的基础，也是估算的基础。教材先安排口算，在扩大学生的口算范围的同时，为学生学习新的估算和两位数乘两位数笔算方法做好必要的准备。并且，在估算和笔算教学活动中，又可以进一步巩固口算。这样，有利于培养、提高学生的计算能力。二、说教学理念1、数学文化观。数学是一种文化，它不仅表现为一个结果，更加重要的是它是人类文明发展过程的一个见证。所以教学上应让学生去经历知识形成的过程，注重学生的经历与体验。
人教版新课标小学数学三年级上册一个因数中间有0的乘法说课稿
8、小结：不管因数中间是否有0，都要用这个一位数去乘多位数里每一个数位上的数，即使十位上是0也要乘。这就是今天我们学习的新知识，因数中间有0的乘法。（板题：因数中间有0的乘法）[设计意图：通过学生的自主探索，获得对“0和一个数相乘得0”的理性认识的基础上，进一步运用估算、口算以及学过的笔算方法上算法上进行探索，中间有0的三位数都是接近整百的数，这为学生运用估算提供了很好的机会。通过估算，能使学生对笔算结果有一个大致的把握，从而可以在很大程度上减少笔算中错误的发生，通过教学，努力使学生感受到：把估算和笔算结合起来，可以提高计算的正确率。逐步培养学生在笔算时自觉进行估算的意识。]三．巩固练习谈话：现在正是小朋友们长身体的时候，所以我们一定要参加体育锻炼呦！今天，我们一起去参加一个智力长跑，好吗？
人教版新课标小学数学三年级上册猜拳游戏中的学问说课稿
想一想：为什么在师生猜拳中老师一直说“5”能赢？为什么选择和多的那队没胜，而选择和少的那队却胜了？选择可能性大的是不是每次一定能赢?选择可能性小是不是每一次一定都输？（至此，本节课到了一个升华层次，学生通过互动游戏、自主探究、讨论分析，从而揭示了“猜拳游戏”中的秘密，对“可能性”的理解达到了一个更高水平，有效地完成了本课重难点教学。）（4）实践验证。实践验证理论。再一次组织学生有目的地猜和,进行实践验证。让理论与实践有机的结合（三）拓展创新，内化提升。儿童用品商店将要举行促销活动，凡到商店购物的顾客都可参加《转盘转转乐》活动。每位顾客可转两次，用两次指针所指数相加得到一个和，不同的和能得到相应的奖项。

人教版高中英语必修4A taste of English Humor说课稿3篇
Then I would ask them to think of a funny English or Chinese and tell it to partners. While telling stories, they can use expressions and some acting to help make the story funny. 5 minutes would be given to do this.Those stories they told there will be the material for their writing. Soletting them tell it at first is helpful. And they can make a difference between telling a funny story and writing it down. Generally speaking, it is difficult forstudents to write well because they don’t know what to write and how to write. Asking them to tell their own stories at first can help them come up with what to write.After their telling, I would invite someone to share his/her story with all of us and I would write it down on the blackboard.This example story would be used as a sample to illustrate the format of funny story. Different from a story from teacher or textbook, a story from students can obviously become a interesting material to draw students’ attention.Then I would ask the whole class to put this story into several parts. It might be a little bit difficult for them. So I would ask them to find out whether all the sentences are necessary. After delete some sentences, there are 6 sentences left behind. Then they can easily put them into three parts. After interaction with students, I would teach them the right terms for each part and conclude the format of funny story.This step is the key and difficult point in my lesson. So I mainly usetask-based teaching method in this part and the task for students was divided into several stages. With the separated difficult level, students can find there are usually three parts in writing. They can also learn to write without the unnecessary parts in the process of analyzing. And then I wouldn’t rush to tell them the right terms to them directly. Instead, I would ask them to name them by their own. A confused mind is better for acquiring knowledge.While-writing:Then I would give students 7 minutes to write down this story, without other requirements.With all the preparations in pre-writing, students’ difficulties were cleared. So it would be much easier for them to write down the story within 7 minutes. There are no other requirements because students’ first writing is actually a drafting. It would be revise and edit several times later. Writing, as a skill
