1、教學(xué)主題圖。（1）讓學(xué)生獨(dú)立觀察教材情境圖。思考問(wèn)題：[1]這幅畫(huà)面是什么地方？[2]你發(fā)現(xiàn)了畫(huà)面中有什么活動(dòng)內(nèi)容？（按順序）（2）在小組中互相說(shuō)一說(shuō)自己觀察到了什么內(nèi)容。你想到了什么？（3）各組代表匯報(bào)。（4）教師板書(shū)學(xué)生匯報(bào)的數(shù)據(jù)。[1]這是某個(gè)校園里的活動(dòng)情景圖。從圖中發(fā)現(xiàn)了教學(xué)大樓前面的兩樹(shù)之間都插著4面不同顏色的旗子，升旗臺(tái)上也飄著一面國(guó)旗。[2]運(yùn)動(dòng)場(chǎng)上每4人一組小朋友在跳繩。[3]籃球場(chǎng)上每5人一組準(zhǔn)備打籃球比賽。[4]板報(bào)下面擺的花是每3盆擺一組，旁邊還有很多盆花。（5）根據(jù)上面的信息（條件），想一想能提出用除法計(jì)算的問(wèn)題嗎？大家在小組議一議。
二年級(jí)數(shù)學(xué)下冊(cè)第二單元表內(nèi)除法教案
一、教材簡(jiǎn)析 本單元教學(xué)內(nèi)容主要有：除法的初步認(rèn)識(shí)、用2～6的 乘法口訣求商，解決實(shí)際問(wèn)題。除法的初步認(rèn)識(shí)分兩個(gè)層次：第一，以生活中常見(jiàn)的“每份同樣多”的實(shí)例合活動(dòng)情境，讓學(xué)生建立“平均分”概念。第二，在“平均分”概念的基礎(chǔ)上引出除法運(yùn)算，說(shuō)明除法算式各部分的名稱。用口訣求商遵循由易到難的原則。解決問(wèn)題是結(jié)合除法計(jì)算出現(xiàn)的。首先在除法的初步認(rèn)識(shí)教學(xué)中 孕伏解決問(wèn)題的內(nèi)容。然后在用2～6的乘法口訣求商之后編入了解決有關(guān)平均分的實(shí)際問(wèn)題和需要用乘法和除法兩步計(jì)算解決簡(jiǎn)單實(shí)際問(wèn)題的內(nèi)容。
二年級(jí)數(shù)學(xué)下冊(cè)第九單元數(shù)學(xué)廣角推理教案
1，猜一猜 師：這里有一個(gè)盒子，盒子里有一朵花，誰(shuí)能猜出這朵花是什么顏色的？盒子里的花兒的顏色是確定的，為什么你們會(huì)有那么多不同的答案？ ……師：好，老師給一個(gè)提示：紅色和黃色。會(huì)是什么顏色呢？師：要想準(zhǔn)確猜出球的顏色，有一個(gè)統(tǒng)一的答案，怎么辦？ 師：滿足你的愿望，第二個(gè)提示：不是紅色的。2、猜球游戲： 小朋友看，老師這里有一個(gè)白色和一個(gè)黃色的乒乓球，現(xiàn)在把它們放到盒子里，我們一起來(lái)玩一個(gè)猜一猜的游戲，好嗎？ 師：我摸出其中一個(gè)，你猜猜是什么顏色的球呢？師：猜得準(zhǔn)嗎？老師給你們一些提示吧：我摸出的不是黃球，那我摸出的是什么顏色的球？你是怎么猜的？師：那盒子里面的是什么顏色的球呢？你是怎么猜的？小朋友們很聰明，根據(jù)老師的提示能準(zhǔn)確地判斷出球的顏色，這種方法就是我們今天要學(xué)習(xí)的簡(jiǎn)單的推理。
