課題：長方形 正方形

教學目的

1．使學生知道長方形、正方形；通過觀察和動手操作，使學生能辨認和區別出這兩種圖形．

2．使學生初步建立起空間觀念，培養學生初步的邏輯思維能力，滲透分類統計思想．

3．激發學生學習數學的興趣，進行愛祖國、愛科學的思想教育．

教學重點和難點

知道長方形和正方形的形狀和名稱，并能區別這兩種圖形．

教學過程

一、導入新課．

同學們，今天老師給大家帶來了一位新朋友，大家鼓掌歡迎！（出示動畫“認識圖形”）

二、講授新課．

1、初步認識長方形（繼續演示動畫“認識圖形”）．

（1）師：這是圖圖提出的第一個問題：“圖形國是什么形狀的？”誰來回答？

（2）教師出示國旗圖，問：國旗的面是什么形狀的？舉起數學課本、練習本問：數學課本、練習本的面是什么形狀的？再拿出一張長方形彩紙，先橫著放，問：這張彩紙是什么形狀的，豎著放、斜著放呢？

（3）學生舉例．

小結：以上這些物品的面，不管大，還是小，它們的形狀都可以用這樣一個圖形表示，（教師畫長方形）問：這是什么圖形？（板書長方形）

（4）數一數長方形有幾條邊，再數一數桌上的長方形紙有幾條邊，用彩筆逐一勾出四條邊．

（5）師用一定長來量長方形的四條邊，學生認真觀察后，問：長方形四條邊一樣長嗎？哪兩條邊一樣長？哪兩條邊不一樣長？

小結：長方形四條邊不一樣長，對著的兩條邊一樣長．

（6）學生折紙，看看是不是對著的兩條邊一樣長．

（7）反饋練習：請說出幾號圖形是長方形．

2、初步認識正方形（繼續演示動畫“認識圖形”）．

（1）這是圖圖提出的第二個問題，誰來回答？

（2）教師拿出一塊手絹，問：這塊手絹是什么形狀的？再舉起地板磚、正方形電光紙，問這些東西的面是什么形狀的？斜著放呢？

（3）學生舉例．

小結：以上這些物品的面不論大或是小，它們的形狀都可以畫成這樣一個圖形“□”（畫正方形），這是什么形？（板書正方形）

（4）數一數正方形有幾條邊，四條邊一樣長嗎？先量一量，再折折桌上的正方形紙比一比．

（5）長方形和正方形比較：①長方形有幾條邊？正方形有幾條邊？②長方形四條邊怎么樣？正方形四條邊怎么樣？③長方形與正方形相同的地方是什么？不同的地方是什么？

教師歸納：長方形有四邊條，正方形也有四條邊，這是相同的地方；不同的地方是長方形對著的兩條邊相等，正方形四條邊都相等．

（6）反饋練習：

用4根小棒擺一個正方形，用6根小棒擺一個長方形．

教師歸納：長方形沿中間虛線對折后，有的是長方形，有的是正方形，為什么呢？這是根據長方形邊的長短確定的，這個問題我們在以后的學習中再進一步研究．正方形不論是大正方形還是小正方形，沿中間虛線對折后都是長方形，沿正方形對角線對折后是三角形．

三、課堂練習．

做一做1、2題

1．沿虛線折一折，看看正方形的邊長怎么樣，長方形的邊長怎么樣（分組進行）．

板書設計

課題：跳繩

教學目標

1．探索并掌握兩位數減兩位數退位減的計算方法，進一步體會計算方法的多樣化.2．發展初步的估算意識和解決生活實際問題的能力.3．培養學生認真計算反復檢驗的好習慣.教學重點

幫助學生理解并掌握用豎式計算的方法.教學難點

掌握連續退位減法的計算方法.課前準備

課件、圖片、實物投影儀.教學過程

活動一：創設情境、引入新課.師：同學們，你們喜歡跳繩嗎？你能說說你的跳繩成績嗎？跳繩不但是一項很好的體育活動，它里面還藏著許多的數學問題呢，你們發現了嗎？

[點評]利用“跳繩”這一情境導入新課，可以體現數學來源于生活實際。利用學生身邊的事情或學生感興趣的事情創設學習情境，可以激發學生的學習興趣.活動二：利用跳繩的情境，討論計算方法.出示主題圖及統計圖表，提出數學問題.這是三名同學跳繩情況的統計表，說說你從表中知道了些什么？

根據這張統計表，你能提出哪些數學問題？

A．小東、小紅共跳多少下？三人一共跳多少下？

B．小東比小紅多跳幾下？小紅比小亮少跳幾下？

??

③要想知道“小東比小紅多跳幾下”你會解答嗎？

板書：小東比小紅多跳多少下？ 62—48＝

[點評]在這一環節，讓學生看懂圖的意思，在此基礎上提出問題，培養學生從實際生活中提出問題的能力，體會數學問題從生活中來。同時學生自己提出的問題更樂于自己解決.2．根據算式，合理進行估算.師：請你估計一下，小東比小紅多跳幾下？說說你是怎樣估算的？

（培養學生的估算意識.）

3.探索算法，合作交流.（1）學生獨立思考算法，試算62－48＝（）

[點評]在這個環節中，學生自己探索計算62－48的方法，發揮了學生的主體性，讓學生親身經歷知識結論的形成過程，發展了學生的思維.算法多樣化充分關注學生的個體差異，讓學生根據自己的情況在原有基礎上提高，又注意了算法的優化，使學生從比較中選擇更簡便的方法.學生可根據自己的實際靈活處理，在口算與豎式中任選一種.（2）將全班分4人小組交流算法，組長統計算法.在全班評選想出算法最多的小組.[點評]進行小組之間的競爭，可以極大地調動學生的學習積極性，提高學生的主動參與意識.（3）全班學生交流算法.算法一：62－40＝22 算法三：62－42＝20

22－8＝14

20－6＝14

算法二：62－50＝12 算法四：58－48＝10

12+2＝14

10＋4＝14

師：好多同學都能口算出算式的結果，除了口算你還能用筆算的方法計算嗎？

算法五：用豎式計算.我發現同學們筆算時有兩種結果，大家看：一種是62減48等于14；

另一種是62減48等于24.到底哪一個結果是正確的呢？我們一起擺小棒驗證一下

[點評]學生通過數小棒，直觀感知當個位不夠減時需再十位借“１”的意義.通常學生先擺62根小棒，再從62根里去掉48根，先去掉8根，2根減8根不夠減，就從6捆中拿出一捆拆開與2根合起來，從12里去掉8根還剩4根，原來有6捆，拿出１捆后還剩5捆，再去掉4捆剩１捆，從而得出結論62根減48根，還剩14根.4．試一試.①小紅比小亮少跳幾下？ □○□＝□（下）

②小亮比小東多跳幾下？ □○□＝□（下）

看圖列出算式，運用自己喜歡的方法計算.5．想一想.趙老師跳了100下，你能知道老師比小紅多跳幾下嗎？

獨立列式.板書：100－48＝

估算得數.說說你是怎樣估算的？

學生獨立解答，小組討論交流.①98－48＝50 ②99－48＝51 ③100－50＝50 ④100－40＝60

50＋2＝52

51＋1＝52

50＋2＝52

60－8＝52

⑤豎式計算：

你能說說計算過程嗎？

活動三：師生共同總結收獲.師：這節課你有什么收獲？做減法豎式時要注意什么？

生：先把相同數位上的數對齊，再從個位減起.個位不夠減，從十位退1，在個位上加10再減.[點評]讓學生自己總結計算方法，并在相互交流中不斷完善自己的方法，培養學生的創新意識.鞏固練習

【教學重點】讀數與寫數的方法。

【教學難點】能正確地讀、寫出100以內的各數。

【教學過程】

一、新授課

1．數一數有多少根小木棍 ？

（1）一個一個地數。（2）十個十個地數。2．學習整十數和非整十數

（1）出示課件，學習整十數，完成相關練習

（）個一是一十，十里面有（）個一。（）個十是一百，一百里面有（（2）出示課件，學習非整十數。）個十。

一個十和2個一組成（）。十和5個一組成（）。75里面有（）個十和（）個一。

3．教師報數，學生擺小棒16、25、50、68．

二、活動二，通過計數器加深認識數的讀寫。

1．出示計數器。十位、個位

教師：計數器從右邊起，第一位叫個位，第二位叫十位，并在計數器分別貼上。

2．教師出示2捆鉛筆和4枝鉛筆。

這里共有幾枝鉛筆？（有24枝），有幾個十枝和幾個一枝，（2個十枝和4個一枝），學生回答后，教師分別把2捆鉛筆和4枝鉛筆分別掛在十位和個位上，接著問：“計數器上應該怎樣表示呢？”啟發學生說出2捆鉛筆表示2個十，在十位上撥2顆珠子，4枝鉛筆表示4個一，在個位上撥4個珠子表示。

寫數時，要先寫十位，再寫個位。十位上是幾，就寫幾；個位是幾，就寫幾，這個數寫作“24”。

讀數時，先讀十位數，再讀個位數。十位上是幾，就讀幾十；個位是幾，就讀幾，這個數讀作二十四。

3．小結。

寫數、讀數都要從高位起，按數位順序寫，個位或十位上一個也沒有寫數時要寫“0”占位。

三、鞏固練習。

“做一做”第2題。

學生獨立完成，教師提問個別同學：該如何寫數，你是怎么想的？集體訂正。

兩位數減一位數和整十數（不退位）

1．使學生學會兩位數減一位數，整十數不退位減法的口算方法，并能正確的進行口算。

2．使學生掌握兩位數減一位數、整十數的思維過程，提高計算能力。

教學重點：掌握計算方法，提高計算能力。

教學準備：課件。

教學過程：

一、談話引入，激發學生學習興趣

師：六一快到了，很多小朋友都想了很多的方式來慶祝，有的小朋友想去公園，有的小朋友想用自己攢的零花錢去買玩具呢，我們也和他們一起去看看吧！（電腦出示玩具店的貨架和玩具的標價。）

二、自主探索，提出問題。

1．仔細看圖，提出問題

師：看貨架上都有哪些玩具？你喜歡什么玩具？你從圖上知道了哪些信息？（觀察后指名回答。）

師：貨架下的兩個小朋友在說什么？你知道了什么信息？

師：怎樣才知道左邊的小朋友買大象玩具后還剩多少元？右邊的小朋友還差多少元呢？（用減法算）

師：你知道這么列式嗎？（師根據生回答板書算式）

師：大家會算上面的算式嗎？先在小組里擺一擺，算一算。

2．分組操作，形成思維。

學生擺小棒，教師巡回指導學生操作。

3．信息反饋，抽象算法。

師：大家擺出了上面兩道題的得數嗎？誰來說一說是怎樣擺的？

師：誰來說一說35-20又是怎樣擺出來的呢？

師根據學生說的板書算法。

師：這兩種算法有什么不同？

4．小結算法。

師：你能根據剛才擺小棒的過程，說一說兩位數減一位數和整十數（不退位）的計算方法嗎？

師：同學們可真棒，我們在計算時一定要看清楚是在個位上去減還是在十位上去減。

三、鞏固練習。

1．完成P68的做一做的第一題

要求：

2．經歷探索兩位數減一位數退位減法計算方法的過程。

3．感受退位減法與生活實際生活的緊密聯系，體會退位減法在生活中的作用。

【教學重點】掌握兩位數減一位數的退位減法。

【教學過程】

一、復習準備

1．口算

2．計算后讓學生說一說自己的算法。

二、引入新課，探索規律

1．引入

師：上面有多少根木棍？現在拿走8根木棍，還剩多少根？

讓學生討論，5比8根少，不夠了，怎么辦呢？同學們，你們會算嗎？

2．下面我們看看小烏龜是怎樣算這樣的題目的：

出示錄像：

師：看過小烏龜計算34－6，你學到了什么，你在計算45－8的時候是不是也用這種方法呢？如果不是，你是怎么算的？

讓學生思考并說說計算的方法。

師總結：我們已經會計算20以內退位減法，運用這種方法我們可以計算100以內兩位數減一位數的退位減法。

三、自主探索

1．引導學生從問題情景中抽象出減法算式。課件出示：第67頁例1中的玩具貨架圖。

師：在例1的學習中我們學會了根據貨架上玩具單價解決“有35元錢，買一個大象玩具，還剩多少元？”和“有20元錢，買一個布娃娃，還差多少元？”等問題，圖上還告訴我們哪些有用的信息？

師：圖上左邊的小朋友說，我有8元錢，想買一輛單價36元的玩具汽車，還要攢多少元才夠，你知道怎么樣算才知道還要攢多少錢嗎？

根據學生的回答，教師在黑板上板書算式：36－8＝？

2．引導學生探索計算方法。

指導學生擺小棒。學生分組擺小棒，并讓他們邊擺邊討論計算的方法。

師總結算法：剛才同學們在小組中討論出了幾種算法，真不錯。在以后的計算中，你喜歡用那種方法就用那種方法計算。

四、鞏固練習

2．完成練習十二的第8題

先讓學生看明確計算任務，然后由學生獨立計算各題的差，最后集體訂正得數。

六、課堂小結

1．小結計算方法。

認識時間

【教學目標】

1．知道大格刻度對應分時表示幾分，會正確讀出、寫出鐘面上的時間，并能根據時間撥出時針和分針。

2．讓學生自己探索看時間的方法，掌握時針走過幾，就是幾時多，分針走過幾小格就是幾分。

3．通過觀察時針和分針走的關系，知道1時＝60分，理解幾時半就是幾時30分。

4．體會時間與生活的密切聯系，培養學生珍惜時間的思想感情。

【教學重點】正確讀出、寫出幾時幾分，會撥幾時幾分。

【教學難點】讀出接近整時的時間，比較快速地說出幾分。

【教學過程】

（一）生活質疑，導入新課

我們已經會看幾時和幾時半，但是在生活中，我們還會看到另外的時間，例如，我們每天是什么時候開始上課的？什么時候下課休息的等等。

這節課我們就來進一步認識幾時幾分這樣的時間，好嗎？（板書課題：認識時間）

（二）探究學習

1．出示課件，認識60小格

師：要正確讀出時間，我們必須了解鐘面。（教師出示圖例或實物）請你說一說，你在這個鐘面上發現了什么？把你的發現和同桌說一說。

學生可能說出：

（1）每個大格里有5個小格，教師問：你是怎么知道的？學生可能說一格一格數的。

（2）共有60個小格，教師問：你是怎么知道的？學生可能不知道如何快速的說出。

教師出示課件進行驗證。

2．認識幾分

師：分針走一小格是1分，時針走一大格是1時。

問1：再仔細看看時針，當時針走一大格的時候，分針走了多少呢？

問2：那么分針走1大格是幾分？你是怎么想的？分針從12走到2是幾分？分針從12走到每個數字各是幾分，你能算出來 嗎？（寫在練習紙上）想想怎么能很快記住每個數字所表示的幾分。

3．繼續認識1時＝60分

我們剛才已經知道，分針走一圈，時針會走一大格？那分針走一圈是幾分？時針走一大格是幾時？這說明1時和60分有什么關系？（板書：1時＝60分）

小結：我們知道了1時=60分，也知道了分針從12走到每個數字各表示幾分了。

4、學習時間

問：現在你能讀出時鐘上的時間嗎？

教師小結：先看時針，時針剛剛走過幾就是幾時多，再看分針，分針走了幾小格就是幾分。

小朋友很能干，下面我們看看這些小朋友的作息時間是怎么樣的？你能填出自己的作息時間表嗎？

（三）鞏固練習

1．看看小斌是怎樣按時上學的，同學們應該怎樣做呢？

2．做一做

問：你覺得一分鐘長嗎？讓學生體會珍惜一分鐘的思想感情。

問：這幾個時間中，你最喜歡哪一個？為什么？這時，再過10分是幾時幾分？15分鐘前是幾時幾分？再過7分又是幾時幾分？

（四）課堂總結

今天你學到了什么知識？怎樣學到的？下課時間到了，請小朋友們看現在的時間是多少？下節上課的時間是多少呢？回家后，把你上午和下午放學到家的時間記下來好嗎？

找規律

【教學目標】

1．通過物品的有序排列，使學生初步認識簡單的排列規律，會根據規律指出下一個物體或下一個數字。

2．通過觀察、擺學具的活動，培養學生的實踐動手能力，激發創新意識。

3．使學生在數學活動中體會數學的價值，體會規律的美和創造的快樂，增強學習數學的興趣。

【教學重點】學生通過實踐活動能發現事物的規律。

【教學過程】

一、展示情景，引入課題

1．師：“六·一”到了，學校組織聯歡會，這是同學們布置的會場，一起來看看吧。

2．課件出示主題圖。

仔細觀察，說說你看到了什么？又發現了什么規律？學生回答。

（1）課件出示彩旗圖。首先來研究彩旗圖中的規律。

生：因為小旗是按照紅色、粉色這樣的順序一直擺下去的，所以粉旗的后面是紅旗。

師：如果讓你給彩旗分分組，好把彩旗排列的規律看得更清楚。你準備怎樣分？誰來指指？為什么這樣分？（小旗就是這樣一組一組重復出現的，規律就看得特別清楚了。）

（2）將錄像停止觀察彩花和燈籠圖。

師：彩旗的規律我們已經找到了，那么燈籠的擺放又有什么規律呢？下一朵彩花下一個燈籠會是什么顏色？該怎么給它們分組呢？把你發現的秘密小聲地告訴同桌。

師：下一朵花是什么顏色的？舉起你的發現。下一個燈籠呢？該怎么分組呢？

二、學習較復雜圖形數字的排列規律

1．根據形狀和顏色的變化發現物體的排列規律。

同學們可真能干，一下子就找到了彩旗、彩花和燈籠排列的規律，根據上面研究的情況，你填一下“下一個圖形會是什么？它是什么顏色的呢？”

學生舉手回答，集體訂正時說說這樣填的理由。

2．根據物體數量的變化發現物體和數字的排列規律

師：小丑要寫出10個有規律的數字，你能幫幫它嗎？

師：下面的圖形排列有一定的規律，試著擺一擺。小組學生交流，派代表進行說明。

三、教師總結

規律在我們的生活中真的是無處不在呀，有規律的事物常給人一種美的感覺，你能發現藏在我們身邊的規律嗎？生回答。（教室的天花板、地板、黑板上的獎品、自己的衣服。）

第四篇：北師大版一年級數學下教學計劃

一年級數學下冊教學工作計劃

一

（二）班

一、學情分析：

本班共有48名同學。在經過了一個學期的數學學習后，基本知識、技能方面基本上已經達到學習的目標，對學習數學有著一定的興趣，樂于參加學習活動中去。

二、教學目標： 本冊教材的教學目標：

（一）數與代數

1、第一單元“加與減

（一）”。是學習20以內的退位減法，降低了一年級上學期孩子們學習數學的難度。退位減法是一個難點，學生掌握比較慢，但同時也是今后豎式減法的重點所在。所以在介紹的：數小棒、倒著數數、湊十法、看減法想加法、借助計數器??這些方法中，孩子們喜歡用什么方法不統一要求，自己怎么快怎么算，但是要介紹這些方法。

2、第三單元“生活中的數”。通過數鉛筆等活動，經歷從具體情境中抽象出數的模型的過程，會數，會讀，會寫100以內的數，在具體情境中把握數的相對大小關系，能夠運用數進行表達和交流，體會數與日常生活的密切聯系。

3、第五單元“加與減

（二）”，第六單元“加與減

（三）” 在“加與減”的學習中，結合生活情境，學生將經歷從具體情境中抽象出加減法算式的過程，進一步體會加減法的意義；探索并掌握100以內加減法（包括不進位、不退位與進位、退位）和連加、連減、加減混合的計算方法，并能正確計算；能根據具體問題，估計運算的結果；初步學會應用加減法解決生活中簡單問題，感受加減法與日常生活的密切聯系。

（二）空間與圖形

1、第二單元“觀察物體”。學生將通過觀察身邊的簡單物體，初步體會從不同角度觀察物體所看到的形狀可能是不同的發展空間觀念，2、第四單元“有趣的圖形”。學生將經歷從上學期立體圖形到現在平面圖形的過程，認識長方形，正方形，三角形，圓等平面圖形，通過動手做的活動，進一步認識平面圖形，七巧板是孩子喜歡的拼圖，用它可以拼出很多的圖形，讓孩子們自己動手拼，積累數學活動經驗，發展空間觀念能設計有趣的圖案。

（三）實踐活動

本冊教材在第五單元之后安排了一個大的實踐活動，即“分扣子”和“填數游戲”。旨在綜合運用所學的知識，從根據事物的非本質的、表面的特征把事物進行分類，發展到根據客觀事物抽象、本質的特征進行不同方式的分類，促進孩子邏輯思維能力的發展。同時，安排學生填數游戲，旨在對孩子的口算能力、邏輯思維能力和觀察能力的訓練，感受數學的樂趣！

三、教學重點和難點

這冊教材的教學重點是：100以內數的認識，20以內的退位減法和100以內的加減法口算。在學生掌握了20以內各數的基礎上，這冊教材把認數的范圍擴大到100，使學生初步理解數位的概念，學會100以內數的讀法和寫法，弄清100以內數的組成和大小，會用這些數來表達和交流，形成初步的數感。100以內的加、減法，分為口算和筆算兩部分。這冊教材出現的是口算部分，即兩位數加、減一位數和整十數口算。這些口算在日常生活中有廣泛的應用，又是進一步學習計算的基礎，因此，應該讓學生很好地掌握。同時，教材結合計算教學，安排了應用所學計算知識解決問題的內容，讓學生了解所學知識的實際應用，學習解決現實生活中相關的計算問題，培養學生用數學解決問題的能力。

教學難點：100以內的加減法口算，購物，以及數學思維的訓練。

四、本學期提高教學質量的具體措施

1、從學生的年齡特點出發，多采取游戲式的教學，引導學生樂于參與數學學習活動。

2、在課堂教學中，注意提問時適當降低難度。應該考慮學生實際的思維水平，多照顧中等生以及思維偏慢的學生。

3、布置一些比較有趣的作業，比如動手的作業，少一些呆板的練習。

4、及時進行學習水平反饋，及時查漏補缺。

5、加強家庭教育與學校教育的聯系，適當教給家長一些正確的指導孩子學習的方法。

6、一定要注意保護學生的自尊心和學習的興趣。培養學生學習的良好習慣

7、課堂主要是提高學生能力

8、讓學生在生動具體的情境中學習數學。

9、引導學生思考，并與同伴進行合作交流。

10、培養學生初步的提出問題和解決問題的能力。

第五篇：新北師大版小學一年級下數學圖書館教案

一年級下數學《圖書館》教案設計

【教學目標】

1.在問題情境中探索并掌握兩位數加一位數進位加法的計算方法，在交流與比較中優化出適合自己的算法。

2.體會解決問題策略的多樣性，培養學生獨立思考的能力和思維的靈活性。

3.在學習活動中養成動手操作、明確表達、認真傾聽和獨立思考的良好習慣。

4．提高學生探索問題的能力，鼓勵學生與他人積極合作學習。【教學重點】

探索并掌握兩位數加一位數的進位加法的計算方法，初步體會計算方法的多樣性。

【教學難點】理解不同算法的算理，尤其是滿十進一的運算規則 【教學過程】

(一）課前活動

1、搶答，口算。29+1

40+3

30+13 8+4 8+9

20+16

2、填空

（1.）

十個一是（）個十。

（2.）

一個十是（）個一。

（3.）

28里面有（）個十和（）個一。

(二)情境導入

1.同學們喜歡看課外書嗎？今天老師想帶大家去我們學校的圖書館看看（板書課題：圖書館），2.圖書館是一個知識的海洋，在圖書館的一角，老師發現了一些適合同學們看的書，請同學們看看，從這一幅圖中，你得到哪些數學信息？

《童話世界》有28本、《海底世界》有9本 生2： 《叢林世界》有4本、《咪咪學院》有8本: 師：根據我們得到的數學信息你能提出哪些能用加法計算的數學問題呢？

生1：《童話世界》和《海底世界》一共有幾本？

生2：《童話世界》和《叢林世界》一共有幾本？ 生3：《童話世界》和《咪咪學院》一共有幾本？

3.我們班的小朋友真能干，一下子就提出了這么多的數學問題，下面我們先來解決這個問題：《童話世界》和《叢林世界》一共有多少本？4.你能列出算式嗎？ 生：

28+4= 5.探究算法

（1）同學們可以借助小棒擺一擺，思考28+4的計算過程（2）誰愿意把你的方法介紹一下。

算法一：學生上臺演示數小棒，先擺28根，再擺4根，把4根里的2根和28根湊成30根，再加上2根，一共是32根。板書：28+2=30 30+2=32

算法二：先算8+4=12，再算20+12=32。（板書：8+4=12 20+12=32）

算法三：計數器。同時課件演示。（先在計數器上撥出28，然后再一個一個在個位上加珠子，個位滿十個珠子怎么辦？個位上十個珠子是十位上一個珠子，我們就可以在十位上加一個珠子，個位上就沒有了。我們把個位上的十個珠子加到十位上，我們把它叫做滿十進一。即從個位算起，滿十進一。然后接著在個位上撥兩個珠子，最后結果就是32.(板書：計數器)算法四：列豎式。用豎式計算，寫得時候要注意什么呢？

數位對齊，個位對個位，十位對十位。

師：8+4=12滿十怎么辦？滿十進一

怎樣記不會忘了進一？進位寫在十位和個位的中間，個位2寫下，再算十位和進一相加。

（3）小結。小朋友真棒，能想出多種方法來計算28+4=32。師：其他兩個問題：

《童話世界》和《海底世界》一共多少本？、《童話世界》和《咪咪學院》一共多少本？

選擇其中的一個，先列出算式，再用你喜歡的方法，動手算一算。

師：坐完后，同桌小聲交流你是怎么算出來的。

三、練一練 1．書本第69頁第一題，圈一圈，算一算

2．書本第69頁第二題，用豎式計算：
