(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.(學(xué)生拿出事先給他們準(zhǔn)備的圖形) good. oh, we all have many shapes.right?(板書課題： shapes) 一. 教學(xué) shape shapes 1. shapes shapes i like shapes 2.（分跟讀、男生讀、女生讀、小組讀、兩個一起讀等方式教會學(xué)生讀法） 3. 介紹上課比賽規(guī)則：what colour is this shape? these shapes are very beautiful, and they’re very useful. they can make many beautiful pictures. look, (課件出示有各種圖形拼出的漂亮的圖片) 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、教學(xué)過程： 1、教學(xué) 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. (在這邊回答時，部分學(xué)生可能會回答it’s a star.，要注意區(qū)分好兩者的不同之處) t：oh, yes, it’s a rubber.but what shape is the rubber?(板書what shape is it? it's a…)同時，教學(xué)字母ar組合，通過car等單詞進(jìn)行疏通理解。 (操練句型) t: (出示兩個五角星) what shapes are …?they’re ….（板書）運用五角星、國旗等操練句型：齊讀、男生問，女生問，分小組問，兩人問，學(xué)生問，開火車問等方式操練。（本部分重點不在于教學(xué)單詞star stars，這個單詞學(xué)生并不陌生，關(guān)鍵是句型的操練，為接下來的新授單詞作好鋪墊）2、教學(xué)rectangle rectangles t: boys and girls, look, this is a rubber, do you have a rubber?now please take out your rubber. (快速找到一塊長方形橡皮)look, this is a star, is this a star? oh, no, what shape is this? it’s a recangle.（板書）運用課本、桌子、國旗直尺等操練句型what shape is it? it's a…。what shapes are …?they’re …在這一環(huán)節(jié)，可讓學(xué)生自己去發(fā)現(xiàn)生活中的長方形，運用句型進(jìn)行work in pairs. 因為rectangle這個單詞對于學(xué)生來講，掌握起來稍微有點困難，我把這個單詞做了音標(biāo)上的分解，并且，angle的發(fā)音對于后面的triangle的發(fā)音會有很大的幫助，故而須把這個單詞基礎(chǔ)打好，打?qū)崱?、教學(xué)square squares t:(出示兩張能拼成正方形的長方形)now, look, what shapes are they?is this a rectangle?(no) but what shape is this? it’s a square.(板書),講解并舉例輕輔音濁化skate ski start, 通過動作演示，出示實物學(xué)生找等方式練習(xí)句型，拼讀單詞。4、教學(xué)diamond diamonds t:(通過一個可以活動的正方形框架來演示拉出一個菱形)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. (這個單詞學(xué)生較難讀好，特別是ia的發(fā)音，須多舉例如violin quiet等，還有ds的發(fā)音，舉例如birds,hands等并告訴學(xué)生發(fā)音規(guī)律。通過撲克牌復(fù)習(xí)長方形rectangle,并運用方牌里菱形標(biāo)志，和三菱汽車（課件）等練習(xí)句型，并簡單介紹三菱汽車。5、教學(xué)triangle triangles t:(通過菱形對折后成三角形進(jìn)行教學(xué))is this a diamond?(no)it’s a triangle.(可讓學(xué)生在前面的基礎(chǔ)上自己先猜讀) 通過三角板，紅領(lǐng)巾，禮品盒等物品練習(xí)句型what shape is it? it's a…。what shapes are …?they’re … 6、教學(xué)circle circles t:(教這個單詞時，我直接通過一個圓圓的笑臉導(dǎo)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.) 通過奧運五環(huán)，奧迪汽車等練說句型。在新授完六個單詞后，我設(shè)計了如下練習(xí)：五、鞏固練習(xí) 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___) 這個游戲中，我給出六個貼著各種圖形的小紙盒（里面裝著各種形狀的禮物），通過師問生答，生問生答，小組問生答等方式進(jìn)行句型的鞏固操練。 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.(校對答案)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.
