2.An auction 拿一个大的洋娃娃进行拍卖，每次竞价增加值不得超过10美元。出价最高的学生能够获得。[设计意图]这两个学习任务贴近学生生活，是学生感兴趣的活动，具有真实性。学习过程就是在教师的引导下，学生用所学的语言交流的过程；在大量习得语言的基础上学习语言。教学活动以学生为主体，以主题为线索，以活动为中心，让学生通过做事、通过思考、通过合作来体验语言，体验生活，体验学习的过程与快乐，在“用”中发展思维能力、创新意识和各种语言运用能力。同时注意对学生的评价，激励学生的学习积极性。

Step 6 Summing up/Homework(3 minutes)1． 学生自己总结本节课所学内容（可自由发言及补充）

T：What did we learn in this class? What activities(活动)do you /don’t you like? Why? 2．总结各组得分情况，评出获胜小组。3．Homework: 1)Teach pupils’ parents to calculate and say their lucky numbers 2)Copy the new words and sentences [设计意图]让学生有机会自主总结，帮助学生梳理知识要点。问题的提出拓展学生的思维，并有助于他们课后的自觉运用。

教学反思：

下面我从三点来谈谈这节课的特点；

一、采用“任务型”活动途径和互动式的语言教学，并进行拓展延伸，学“活”知识，激“活”知识和引“活”成就。本节课采用“任务型”活动途径和互动式的语言教学，配合使用图文并茂、声形兼备的多媒体课件，强调个人参与、二人结对和小组参与的活动方式。学生在每个环节都能明确感受到自己的学习任务，主动参与和探讨。“任务型”教学不是为 显示学生的语言技能，而是为了交换信息，特别是在个人之间进行。在学生完成一个任务时，学生在不同的角色转换中其注意力也在转移。

二、创设生活化课堂，进行多样化教学。

英语教学的真正目的，不是单单达到对知识的理解，而是能将所学运用生活，尤其是创造性地运用。如何让学生懂得享受学习带来的乐趣呢？生活化课堂教学需要有丰富、多样化的教学活动。在这节课中，我设计了一个模拟购物的情境，课前我要求学生带物品，例如：衣服、食物、书籍、玩具等各种各样的东西。当进行这个活动时，把学生分为八大组，让小组成员间进行买卖交易，每组由两个同学负责做售货员，其它同学进行购物。进行活动所使用的语言是本节课所学过的句型、单词，并鼓励学生进行情境性的创造会话。学生的积极性完全被激活了，他们一方面沉浸于真实愉快的气氛中快乐说英语，真正成为学习的主人——主动说英语、大胆说英语，一方面又在积极思考这些他们在生活中所熟知的事物该如何用英语表达。在这样轻松愉快的情境，能缩短课堂与生活的距离，让学生将知识创造性地运用，取得了很好的教学效果。遵循了学生活中的英语，在英语中学生活。

三、巧设游戏，一石激起千层浪。最后的一个活动是拍卖会，这是一项很有意思的活动，它是贴近生活而对学生来说又是十分新鲜、刺激的，每个学生都是活动的参与者。我在组织这一环节的时候，一开始学生的注意力就非常集中，因为他们都感觉到这会是一个很有趣的活动。在这个过程中，我认为我做得比较好的一点是，能够注意到从语音、语调方面激发学生竞价的心理与热情。对物品的竞价，是需要学生的思维转向的，通过竞价，不仅帮助更熟练地掌握对数字的表达，而且调动了学生强烈的参与意识，气氛十分热烈，把本节课的气氛推向了高潮。

上完这节课后，引起我思考的问题是：“完成教学任务”的真正涵义是什么？这堂课我原定要把课文内容跟录音读一次的，但由于学生在购物情境当中努力争取表演的机会，这一教学计划没有完成到，可课后冷静地思索，却发现孩子们主动学会了表达比课文内容更多的东西。，Draw, cut and play!(WB p.70)Ss draw a picture in each box.Then Ss cut their cards apart and choose one card.T say the word and listen for another with the same sound.T demonstrates by holding the card ice cube and giving a student the card humans.T and S1 walk around the room in different directions, calling out their words.T cups his/her ear with one hand, pretending to be listening, then moves towards S1.They sit down together, showing the class their cards.Then all Ss play pretending to be listening, then moves towards S1.They sit down together ,showing the class their cards.Then all Ss play.Song activity Write day, week, month and year on the board.Sing the first two verses of the song How often do you go fishing? But as you do, mime the activities hiking and dancing, as well as showing the correct number of fingers and pointing to the correct words in order to prompt the Ss to sing the song correctly.Continue to sing the song, but invite Ss to come forward to lead the class by miming, showing their fingers, and pointing to the correct word on the board.Activity 5 Divide the class into two teams.Start to talk about yourself, just as the frog, polar bear, and girl do in Activity.Then ask questions to elicit answers, such as What’s my name? What am I? What do I do? When do I …? How often do I …? Give points for correct answers.Then divide the class into groups of four and have each student talk about themselves, then ask the others in their groups questions for points.Unit Five It’s magic hat.（10月12日）一Teaching objectives: How much is the guitar?

1﹒通过TPR，以动作形式导入—操练新知识，学生有较浓厚的学习兴趣，而且教学效果较好。

2﹒在学习人物的过程中，作示范不够清晰，因此，有部分学生区分不是很清楚，在示范时因示范清楚，直到学生明白为止会更好。

3﹒多媒体的运用，增添了学习的色彩感，效果好。

第二篇：购物教案

购物_--------两、三位数乘以位数

一、情境引入

师：同学们，老师今天特别高兴，因为我要搬新家了。今天我想去家具城买一些家具，你们愿意一起去看看吗？（出示图示）这节课我们就来解决一些有关购物的问题。（板题——购物）

二、主动理解，探索新知

1、理解图意。

师：看，我们已经来到了家具城！这里的家具真多啊！谁能用响亮的声音向大家介绍一下这里都有哪些家具，分别是多少钱呢？

（一个书柜213元、一张桌子42元、一把椅子12元。）

2、提出问题。

师：根据这些信息，你想帮老师选哪种家具呢？你能提出一个用乘法解决的数学问题吗？

预测：

4把椅子需要多少元？2个书柜需要多少钱？3张桌子需要多少元？……

师： 同学们真了不起，提了这么多的数学问题。现在老师家急需4把椅子，要不我们就先来解决这个问题吧？

二、探索交流，解决问题

⒈结合情境进行估算。

师：请你先来估一估，4把椅子大约需要多少元？

预测：把12看作10，10×4=40，大约等于40；

师：继续想，实际计算结果会比40多还是少？怎么想的？

2、具体计算，探索计算方法。

⑴独立计算。

师：我们估计结果比40元多一些，那实际结果究竟是多少呢？轻拿出练习本，把计算过程试着写出来。

学生在准备好的本子上独立计算，书写计算过程。教师巡视，了解学生情况，指导帮助个别学生，留意同学计算的各种方法，请不同方法的同学板演。

师：已经完成的，可以再想想其他的计算方法，也试着写下来吧。⑵同桌交流。

师：我发现，有的同学的方法很好。现在请同桌两人相互看一看，轻声地交流一下，你一定会有所收获的！

生同桌交流。

⑶全班共享。

师：请大家先坐好，看谁坐的最直。下面一起来分享这几种方法，先请他们介绍，看看这些方法和你的有什么不同，思考一下他们的方法好在哪儿？

引导学生介绍算法，组织学生倾听，互评。

预测：

①口算（乘法分配律）

10×4＝40 2×4＝8 40+8＝48

教师随着学生的介绍：你的意思是说，先算4个10元的是40元；再算4个2元是8元，最后把40元和8元合起来，是48元。（板帖人民币图片）

师：很好的口算方法！谁听清楚了？（生举手示意）真为你们高兴！（对这名学生）看，你语言简洁明了，大家理解起来多容易呀！谁能再来说一说计算的过程？

请一名生再说一说，引导语言简洁、表达清楚、完整。

②连加法口算12+12+12+12＝48

师：可以用加法来算吗？怎么想？12×4表示求4个12的和是多少，可以用连加的方法来计算！

师：还可以怎么算？（加法竖式）

师：看着竖式，再来说一说计算的过程。

指一生说一说，说清竖式计算的过程：先算个位4个2，得8，个位写8；再算十位，4个10得40，十位写4；得数就是48。

③乘法竖式笔算

其实，在我们数学中，不光加减法有竖式，可以用竖式计算，乘法算式也可以用竖式计算，师：下面请用竖式计算的同学来介绍，请大家和老师一起仔细听，你对竖式计算中不清楚的地方，可以在他介绍后提出来，看谁是最会提问的孩子！

学生介绍，其他的学生提出疑问，在问和答中明晰算理。

对于这些问题，学生可能还是表达不够清楚，教师引导学生和口算的方法进行对照：回头看一下，这里的1表示多少？（10元）乘4在算什么？（在算4个10元）所以，4写在十位上。学生会发现竖式计算时与口算一样，都是先分别算出10×4和4×2的结果，再把这两部分合在一起，明晰竖式计算的算理和过程。

再联系前面的加法竖式来帮助理解每一步的计算。

在计算12×4之前，我们先将乘法竖式和以前学过的加法竖式来做一对比，（出示课件）请你仔细观察一下，在这个连加算式中，个位上的8是怎么得到的？对了，是2+2+2+2＝8得到的，也可以说是2×4＝8得到的，那么在用乘法竖式计算时，用个位上的2和4相乘，因为有4个2，所以2×4＝8，8个1,所以在个位上写8。再来看连加竖式十位上的4是怎么得到的？对，是1+1+1+1＝4得到的，也可以说是1×4＝4得到的，用乘法竖式计算时，用十位上的1和4相乘，因为十位上的1表示1个十，1个十和4相乘就得到4个十，因此要在十位上写4。小朋友，你听明白了吗？老师有问题要问了？你知道4乘十位上的1得到的数，为什么写在十位上吗?给你的小伙伴说一说吧！对了，因为4乘十位上的1表示4个10相乘，是40,所以得到的4应该写在十位上。这样，12×4＝48(元)，答：买4把椅子需要48元钱。

小朋友，赶快和你的小同桌说一说12×4怎么得到的48？好，说完了吗？12×4，要从个位乘起，二四得八，在个位上写8，再算十位，一四得四，十位上写4，所以12×4＝48。和你刚才估算的结果接近吗？

师：通过同学们的介绍、提问及这些方法之间的联系和比较，我们发现计算的过程基本上是一致的。比较一下乘法竖式和加法竖式还有口算方法，哪种用起来更方便呢？（竖式）看来，竖式正是用来记录这几种计算方法，它书写简化，也就使计算更加简便了，同学们一定要认真掌握竖式计算的方法。

师：还有谁是用竖式计算的？请××同学再来说一说，老师来写，请同学一起再看一下竖式的书写格式及过程。

再请一名同学说过程，教师示范板书，明确竖式的书写格式及过程。

对于计算过程，学生只要大致说清即可：先写第一个乘数12，对齐个位写第二个乘数4，在4的左面写×，然后用尺画一条横线。先用12个位上的2去乘4，等于8，个位上写8；再用12十位上的1去乘4，等于40（或是4个10），十位上写 4；结果48。

师：这么多不同的计算方法，真是一个美好的分享！其实，无论是哪种方法，都是把两位数乘一位数的计算转化成了整十数乘一位数和表内乘法等我们已经学过的计算，算起来就容易多了。这是很重要的转化的学习方法，以后在接触新计算问题时，同学们都可以用这种方法试一试，相信你们会做得很好。

师：把计算结果和先前的估算结果对照一下，差不多吧。结果是48元，板书得数：48（元），我们一起口答——买4把椅子需要48元。

（二）利用迁移，掌握新知。

现在请同学们利用竖式的方法再来算一算买2个书柜的价钱是多少？

1、学生尝试列算式。213×2=？

请你先估算，再用竖式计算。

在学生独立解答后，说一说你是怎样算的？积中的4、2、6各表示什么意思？

师：为什么4要写在百位？

生：因为这里的4代表的4个百。

师：大家比较一下 42×2和213×2，一个是两位数乘一位数，一个是三位数乘一位数，它们有什么相同的吗？

生：算的方法都是一样的。

师：怎么个一样法？ 生：都是在拆数计算。

师：孩子们今天学得真是不错。真正的弄清了乘法竖式中每一步的含义。那么现在就请大家一起完成这两道题。

小朋友，请你仔细观察这两个竖式，想一想：在用乘法竖式计算多位数乘一位数时要注意什么?

多位数乘一位数，从个位算起，乘到哪一位，就把积写到哪一位上

三、巩固练习，应用提升

师： 小朋友可真了不起，解决了这么多的数学问题，相信你一定掌握两、三位数乘一位数的窍门了吧！下面，老师出几道题考考你，有信心吗？真棒，我们开始吧！

师：小朋友，下面我们先来一个口算小比赛，比比看谁最细心，做起题来又对又快。1、7×3+4 8×6+3 5+2×8 2×6+5 4×9+6 3+6×72、初显身手

竖式计算

3、明察秋毫（改错）欢乐购物

四、总结收获，拓展延伸

师：我们的课就要结束了，通过这节课的学习，你有哪些新的收获？
