四年级英语weather教学设计

1、四年级英语下册unit 3 weather 基于课程标准的教学设计李媛媛一、教学目标1. 知识目标：学生能听、说、认读 sunny, cloudy, windy, rainy, snowy，并能通过探究，掌握这几个词汇读音规律。学生能够了解不同天气的形成过程，并初步学会根据自然界的各种现象判断天气即将发生的变化。2. 能力目标：增强主动思维和实践意识，提高自主学习能力，提高语言运用能力。3. 情感目标：学生通过充分挖掘生活经验，丰富生活知识，认识了解我们赖以生存的大自然。二、课前准备彩色粉笔、课件、录音机三、教学和活动过程教学过程设计说明热身（warm-up）1. lets dot: walk

2、, walk, walk, run , run, run. fly, fly, fly. jump, jump, jump . dance, dance, dance. swim, swim, swim. draw, draw, draw. 中间加入 stop。(学生饶有兴趣地边听边做，听到 stop 时停。)2. 超级变、变、变教师寥寥数笔呈现板书背景（山，河等）t：what can i draw? what do you see?有的学生说：you can draw a mountain. its so big.t:（边说边表演）look, a mountain.t: can you be

3、 a mountain? im a bird. im beautiful. i can fly.what can you be?ss: we can be the yandang mountain. its beautiful.(学生对教师瞬间画成的画很诧异。)tpr 活动既可活跃课堂气氛，又可为下一环节的语言作铺垫。stop 可增加tpr趣味性。趣味盎然的游戏调动学生兴趣，自然导入新知识。又为本课结尾的表演埋下伏笔。呈现/操练（presentation/practice）呈现各种天气现象的形成过程1. 教师在黑板上画一个卡通太阳sun 板书t (引导) ：look, im the sun.

4、im shy. how do you feel? are you hot? 教师边表演边说ss: i feel warm.t: can you be a sun?s1 拉起头发表演怒发冲冠的太阳: look, im the sun. im angry.（众学生笑）教师顺势让学生说出自己的感受。ss: i see the angry sun. im hot.s2 驮着背表演年老的太阳: im the sun. im old. im very kind.ss: oh, we feel.教师因势利导，让学生发散思维，并复习hot，cold，warm，cool 等词。2. cloudt: look,

5、the sun is shinning in the sky. the water in the river changes into steam. what will it be?教师画云ss:云ss学说cloud。板书：cloudt: what does the cloud look like?s1: the cloud looks like babys face. its lovely.s2:the cloud looks like an ufo.it can fly. its cool.t: （课件一 出示各种云的形状图）what does the cloud look like?th

6、e cloud looks like.s1(图片一): the cloud looks like a horse. its strong . it can fly in the sky.s2(图片一): the cloud looks like a cow. its fat.s3 s4 s5.结合科学课知识呈现新知识。学生在学习语言的同时，又在教师的带领下探索自然界的奥秘。给学生一个似是而非的图形，训练学生的发散性思维，充分发挥学生的想象力。不同的答案形成了学生之间的信息差异，学生有表达的欲望，乐于表达。单词操练在句型的依托下更为有效。学生张开想象的翅膀，发散性思维。3. raint: mor

7、e and more clouds get together. what will come?ss: 雨学说 rain。板书：raina. talk about the sound of the rain。s1: rain, rain, hualala.教师接话题t: oh, how heavy! heavy rain, lets go !(教师装着狼狈地逃开,课堂一下子沸腾了,学生纷纷举手模仿雨声。)s2 ：rain, rain, xilili.t: oh, light rain.b. sing the song rain, rain go away.学生的口中导出 rain 一词。教师在课

8、堂中幽默的表演给课堂注入了新鲜的活力，借助学生的话渗透 heavy rain light rain。4. snow教师画冷空气板书：snowss say the chant. snowsnow, snow, where do you go?i dont know. i dont know.where can i go?单词的操练形式可以灵活多样，snow 一词的发音对学生来说较好掌握，因此通过一个朗朗上口的歌谣加以巩固。5. snowya. t: whats the weather like here? its snowy. 板书 /i/, /i/, snowy.b. 区别 snow 和 sn

9、owyt: whats this?t: whats the weather like here?s: its snow.s: its snowy.c. talk about snowy days.t: its snowy. i can make a snowman.s: its snowy. i can make a snow rabbit.师接学生的话题 is it beautiful or ugly? does it have small eyes or big eyes?s1: i can make a snow miss chen.(哄堂大笑)s2: its snowy. i can

10、make a snow tiger. it has two big eyes. the eyes are carrots. the nose is stone. its lovely.(教师表扬，给予肯定)课堂是随机的，学生经常在你不经意的时候给你惊喜，作为教师，应该善于捕捉时机，让学生的思维火花撞击出不同的乐章。6. sunny, cloudy, rainy.a. t:i,i,snowy.i, i .ss: i, i, sunny.t: (课件二 不同天气图)学生在表达自己的思维的过程中，难免会出现一些语病，教师应加以鼓励，而非立即纠正,这正是学生从不自觉的模仿语言到自觉创造语言的良好开端。

11、7. 用有节奏的 chant 来操练rainy rainy, run back home. sunny sunny, play a game.cloudy cloudy, rain is coming.在教师引导下自主探究语音规律得出sunny, cloudy, rainy这几个词的发音。拓展/巩固（extension/consolidation）活动 1t: (.课件三 晴天图) its sunny. i can.t: (.课件四 阴天图) its cloudy. what will the weather be like? ss:it will be.t: (课件五 雨天图) its ra
