4年級(jí)上AUnit3 How many? 教學(xué)設(shè)計(jì)

t:i have a pencil. do you have any pencils?
s1: yes, i do.
t: how many pencils do you have? let’s count. one, two, three…nine.
s1: i have nine.
t: do you have any crayons?
s2: no, i don’t.
t: what do you have?
s2: i have some books.
t: how many books do you have?
s2: i have ...
在free talk中若有學(xué)生回答提前涉及到新授內(nèi)容，比如數(shù)字13~19，教師可以展開新授。
t：if you want to know the number of things, you can ask “how many?”
新授：how many
【設(shè)計(jì)意圖】在師生問答交流過程中滲透how many … do you have?/can i have a look?句子的教學(xué)，讓學(xué)生在游戲中感知、理解并學(xué)會(huì)做正確回答i have… 同時(shí)揭題unit3 how many?
3.出示本課時(shí)教學(xué)目標(biāo)并揭題(ppt呈現(xiàn))
【設(shè)計(jì)意圖】學(xué)生通過本課學(xué)習(xí)目標(biāo)了解今天該學(xué)什么內(nèi)容，明確學(xué)習(xí)目的。
step 2 presentation
1.t: look! i have many things. can you guess what i have?
 (ppt分三個(gè)氣泡呈現(xiàn)：分別是toy animals, fruit, ?)
引導(dǎo)學(xué)生用句型：do you have any…?來猜測(cè)
引出how many … do you have？豐富對(duì)話讓學(xué)生繼續(xù)追問
s1 do you have any…?
t: yes, i do.
s1: how many toy monkeys do you have?
t: i have 11 toy monkeys.
【設(shè)計(jì)意圖】教師提供生活真實(shí)情景，如屏幕上出現(xiàn)娃娃、書等物品，學(xué)生用句型詢問，誰說的又對(duì)又好，教師用耳語的形式告知答案，形成信息溝激發(fā)學(xué)生積極性。
2.同法引出13 oranges新授單詞：thirteen 13
3.t: can you guess what i have?(教師給出？氣泡詢問)so you can ask with this sentence “ what do you have?”
新授并操練： what do you have?
t: i have some stickers.
新授：sticker 貼紙
s: how many stickers do you have?
t: let’s count. ok? my god, too many. boys and girls, if we want to count them, we should know more numbers.
 (ppt 分兩組呈現(xiàn)1~19的數(shù)字拼寫，個(gè)位數(shù)相同數(shù)字兩兩對(duì)應(yīng))
t: what’s this new number? (教師指著13讓學(xué)生朗讀出新單詞) can you try to read the other new numbers? 新授：14~19
【設(shè)計(jì)意圖】新授其他數(shù)字時(shí)，讓孩子自己嘗試讀一讀，觀察一下數(shù)字間的特征，從而自己得出發(fā)音和記憶規(guī)律。并強(qiáng)調(diào)拼寫特殊的幾個(gè)單詞：thirteen, fifteen, eighteen.在新授過后，可利用板書，教師點(diǎn)學(xué)生讀來鞏固。
t：let’s count the stickers.
t: fifteen./ i have fifteen stickers.
step3 story time
t: you did a good job! it’s story time now.
1. 先引導(dǎo)學(xué)生看圖
t: who are they?
t: where are they?
t: what are these? (指著圖畫中玩具和貼紙)
【設(shè)計(jì)意圖】通過指導(dǎo)看圖，幫助學(xué)生學(xué)會(huì)學(xué)習(xí)策略，學(xué)會(huì)抓住重點(diǎn)，并進(jìn)行合理猜測(cè)，有助于聽力找出答案。
1.    watch and answer.
t: great! maybe you can get the stickers. you know miss wu has fifteen stickers. today mike and helen show their things to their friends too. let’s have a look who has fifteen stickers, too.
q: who has 15 stickers?
第一遍讓孩子看動(dòng)畫，對(duì)文章內(nèi)容了解大概找出問題答案。“誰也有15張貼紙？
