(sing a song: little star ) step two: learn and read t: now, my children ,look. there are some shapes in my hands. do you have any shapes? now,please take out your shapes.(学生拿出事先给他们准备的图形) good. oh, we all have many shapes.right?(板书课题： shapes) 一. 教学 shape shapes 1. shapes shapes i like shapes 2.（分跟读、男生读、女生读、小组读、两个一起读等方式教会学生读法） 3. 介绍上课比赛规则：what colour is this shape? these shapes are very beautiful, and they’re very useful. they can make many beautiful pictures. look, (课件出示有各种图形拼出的漂亮的图片) are they beautiful? do you like them? now, listen, this class, if you are good, you can make a beautifui picture too. look, every group has a paper and many shapes. if you are good,you can choose your favourie shape to your paper. and at last, let’s see, which picture is the best beautiful, if you do it, you will be the winner,ok?i think, all of you will be the best. 二、教学过程： 1、教学 star stars t: now, look, this is my friend “gaffey cat”, do you know him? look, this is his pocket, aah, there’s something in it? what’s this? guess? now, please come here and touch it. (在这边回答时，部分学生可能会回答it’s a star.，要注意区分好两者的不同之处) t：oh, yes, it’s a rubber.but what shape is the rubber?(板书what shape is it? it's a…)同时，教学字母ar组合，通过car等单词进行疏通理解。 (操练句型) t: (出示两个五角星) what shapes are …?they’re ….（板书）运用五角星、国旗等操练句型：齐读、男生问，女生问，分小组问，两人问，学生问，开火车问等方式操练。（本部分重点不在于教学单词star stars，这个单词学生并不陌生，关键是句型的操练，为接下来的新授单词作好铺垫）2、教学rectangle rectangles t: boys and girls, look, this is a rubber, do you have a rubber?now please take out your rubber. (快速找到一块长方形橡皮)look, this is a star, is this a star? oh, no, what shape is this? it’s a recangle.（板书）运用课本、桌子、国旗直尺等操练句型what shape is it? it's a…。what shapes are …?they’re …在这一环节，可让学生自己去发现生活中的长方形，运用句型进行work in pairs. 因为rectangle这个单词对于学生来讲，掌握起来稍微有点困难，我把这个单词做了音标上的分解，并且，angle的发音对于后面的triangle的发音会有很大的帮助，故而须把这个单词基础打好，打实。3、教学square squares t:(出示两张能拼成正方形的长方形)now, look, what shapes are they?is this a rectangle?(no) but what shape is this? it’s a square.(板书),讲解并举例轻辅音浊化skate ski start, 通过动作演示，出示实物学生找等方式练习句型，拼读单词。4、教学diamond diamonds t:(通过一个可以活动的正方形框架来演示拉出一个菱形)now,boys and girls, look,this is a square, but is his a square?(no.) yes,this isn’t a square, this is a diamond. (这个单词学生较难读好，特别是ia的发音，须多举例如violin quiet等，还有ds的发音，举例如birds,hands等并告诉学生发音规律。通过扑克牌复习长方形rectangle,并运用方牌里菱形标志，和三菱汽车（课件）等练习句型，并简单介绍三菱汽车。5、教学triangle triangles t:(通过菱形对折后成三角形进行教学)is this a diamond?(no)it’s a triangle.(可让学生在前面的基础上自己先猜读) 通过三角板，红领巾，礼品盒等物品练习句型what shape is it? it's a…。what shapes are …?they’re … 6、教学circle circles t:(教这个单词时，我直接通过一个圆圆的笑脸导入)oh,boys and girls, this class,you’re all very good.now,i want to give you a present.look,a smiling face,give all of you,so every group can get a shape.now,please look here, what shape is this face?(it’s a circle.) 通过奥运五环，奥迪汽车等练说句型。在新授完六个单词后，我设计了如下练习：五、巩固练习 step one:play the game t:now, let’s play a game,ok?(ok) look, there are some shapes here.what shape do you like?(i like___) 这个游戏中，我给出六个贴着各种图形的小纸盒（里面装着各种形状的礼物），通过师问生答，生问生答，小组问生答等方式进行句型的巩固操练。 step two:look and match t:ok.now please take out your paper,listen i’ll give you one minute to do it :look and match.i think you are all very good,now let’s begin. t:are you ready?now please look here.(校对答案)if you’re right,please put up your hands. step three:look read count and answer t:ok.now boys and girls,this class,which group is the winner?please take out your pictures,let’s count it and then answer the questions.now,listen !all of you must speak english ,ok?(ok) 1.how many shapes do you have? we have____________shapes. 2.what are they? they’re________star(s),________triangle(s), _________rectangle(s),_______diamond(s), ________circle(s) and ________square(s). t:so today,group… is the winner. 六、homework 1.copy the new words three times. 2.draw a picure with some shapes.
