一、说教材《8、9的加减法》是小学数学第一册第三单元的重点内容之一,它是在学生学习了7以内的加减法和8、9的认识的基础上进行教学的,是单元的重点,也是本册书的重点内容,甚至在整个小学数学教学中都占有着非常重要的地位,是进一步学习20以内加减法计算最直接的基础。二、说教学目标根据新《课标》的要求、教材特点以及学生的实际情况制定教学目标如下:1、知识与技能:学会根据一幅图能够列出两加两减四个算式。能熟练计算8、9的加、减法。2、过程与方法:通过观察、操作、小组合作学会根据一幅图能够列出两加两减四个算式。能熟练计算8、9的加、减法。3、情感态度与价值观:以小组合作学习的形式培养学生学习数学的兴趣、合作意识和探索精神。
我来到书房,找到了字典,既想快点知晓答案,和妈妈比个胜负,又想慢点儿,万一又错了怎么办。我紧张地翻开字典,找到了“偌”字的读音。天呐,我是对的,我太开心了!(不足1:缺少动作描写,没有展现出“我”的紧张。修改:我使劲地捏着字典,颤抖着双手,慢慢地打开字典。不足2:结尾缺少人物的语言和神态描写,没有展现出人物开心的心理。修改:我眉飞色舞地大叫道:“天呐,我赢啦!我赢啦!”)我捧着字典,连蹦带跳地来到妈妈面前,欣喜若狂地说:“妈妈,你想不到吧,你一个堂堂初中老师,居然败在拼音不太好的女儿手下。哈哈,我终于报‘仇’了……”此时的我,简直比中了五百万还要开心一百倍。妈妈一听便傻了眼,刚才那坚定的神情已经荡然无存,妈妈连忙接过字典看了又看,生怕我看错了似的。看到字典上的读音,妈妈哑口无言。
方法总结:绝对值小于1的数也可以用科学记数法表示,一般形式为a×10-n,其中1≤a<10,n为正整数.与较大数的科学记数法不同的是其所使用的是负整数指数幂,指数由原数左边起第一个不为零的数前面的0的个数所决定.【类型二】 将用科学记数法表示的数还原为原数用小数表示下列各数:(1)2×10-7; (2)3.14×10-5;(3)7.08×10-3; (4)2.17×10-1.解析:小数点向左移动相应的位数即可.解:(1)2×10-7=0.0000002;(2)3.14×10-5=0.0000314;(3)7.08×10-3=0.00708; (4)2.17×10-1=0.217.方法总结:将科学记数法表示的数a×10-n还原成通常表示的数,就是把a的小数点向左移动n位所得到的数.三、板书设计用科学记数法表示绝对值小于1的数:一般地,一个小于1的正数可以表示为a×10n,其中1≤a<10,n是负整数.从本节课的教学过程来看,结合了多种教学方法,既有教师主导课堂的例题讲解,又有学生主导课堂的自主探究.课堂上学习气氛活跃,学生的学习积极性被充分调动,在拓展学生学习空间的同时,又有效地保证了课堂学习质量

Encourage students to use both the job / workplace combinations in the book and the ones that students came up during class discussions. Be sure they have twice as many sets of cards as there are students in the group. They can make two sets of cards for a single job / workplace, if necessary. Then have each group mix up its set of cards and hand their cards out in random order. Each time a student gets a pair of cards that match, he or she can lay these cards down. The goal is to have no cards in your hand at the end.3.

五、教学Section B-2c1. Pair work: What do you think of the belt/sunglasses/…? What does your father/mother/… think of your scarf/belt…?2. Group work(1). Teacher shows some different kinds of school uniforms (制服)and asks : “ What do you think of your school uniforms?

(Why?)What's your favorite game shows?What do you think of talk show?I doesn’t mind it.I like it.I love it.I can’t stand it.3.记录下排在前10位的TV Program,填写调查表,比较其收视率。

单元整体说明(一)单元教材分析本单元的核心话题是描述动物和表达个人喜好,以及句式why do you like…? Because…。这也是本单元的教学重点。通过本单元的学习,学生应能较流利地运用所学词汇和句型描述动物,表达个人喜好。(二)单元知识结构1.词汇动物名称 tiger, elephant, koala, dolphin, etc.词汇描述性形容词: smart, cute, ugly, clever, shy, etc.国家名: Australia, South Africa2.句型Why do you like koala hears? Because they are cute.Where are pandas from? They're from China.What animals do you like? I like dolphins.(三)单元整体目标1.Master the vocabulary2.Master and use: Why do you like koalas? Because they am cute.Where are pandas from? They're from China.What animals do you like? I like dolphins.(四)单元教学重难点一览(五)单元学情分析学生此前已经学过由why, where, what 引导的特殊疑问句句型,具有了学习本单元知识的认知前提。形形色色的动物能激发学生的好奇心,产生了解它们的欲望,这有利于本单元知识的教学和学生学习兴趣的培养。

"Hello! Welcome to English class! Introduce yourself. Meet your new classmates." That's what the teacher says. What do you say? "Oh no!" It can be difficult talking to new people. But it can be fun, and you can make friends. How do you do it? Make small talk. Small talk is polite conversation. "Wang Nan is a great pingpang player, isn't she?" "I'd love to meet her, wouldn't you?" "It's been raining a lot, hasn't it?" Tag questions are a form of polite speech. To make small talk successfully, you should know how to make them. You should also know what topics to talk about. Try to learn this unit carefully. The next time you're in English class, you'll find out. Making small talk's easy, isn't it? (“你好!欢迎你!请做一下自我介绍。认识一下你的新同学。”通常在课上老师会这样说。你会说什么呢?“噢,不!”与陌生人谈话太困难了。但是这也很有意思,并且你还能交到朋友。你该怎么做呢?闲聊。闲聊指得是礼貌的对话。“王楠是一个很棒的乒乓球运动员,不是吗?”“我希望自己能认识她,你呢?“今年的雨水很多,不是吗?”反意疑问句是一种礼貌用语。为了使得谈话成功,你应该知道怎样去进行闲聊。你还应该知道与不同的人该谈论什么样的话题。认真的学习这个单元吧,下次在英语课上,你会发现与大家展开谈话是一件很容易的事情,不信我们来试试。)
