教學(xué)追記：本堂課，在我?guī)ьI(lǐng)著學(xué)生利用教具進(jìn)行操作，在此基礎(chǔ)上，讓學(xué)生自主發(fā)現(xiàn)圓的面積與拼成長(zhǎng)方形面積的關(guān)系，圓的周長(zhǎng)、半徑和長(zhǎng)方形的長(zhǎng)、寬的關(guān)系，并推導(dǎo)出圓的面積計(jì)算公式。教學(xué)環(huán)形的面積計(jì)算時(shí)，我充分放手給學(xué)生，讓學(xué)生通過(guò)思考討論領(lǐng)悟出求環(huán)形的面積是用外圓面積減去內(nèi)圓面積，并引導(dǎo)他們發(fā)現(xiàn)這兩種算法的一致性，同時(shí)提醒學(xué)生盡量使用簡(jiǎn)便算法，減少計(jì)算量。圓的周長(zhǎng)和面積的練習(xí)課教學(xué)目標(biāo)：1、通過(guò)教學(xué)使學(xué)生理解并掌握?qǐng)A的周長(zhǎng)和面積計(jì)算方法。2、培養(yǎng)學(xué)生分析問(wèn)題和解決問(wèn)題的能力，發(fā)展學(xué)生的空間觀念。3、靈活解答幾何圖形問(wèn)題。教學(xué)重點(diǎn)：認(rèn)真審題，分辨求周長(zhǎng)或求面積。教學(xué)過(guò)程：一、復(fù)習(xí)。1、求出下面圓的周長(zhǎng)和面積并用彩筆描出周長(zhǎng)，用陰影表示出面積。

4．操作。（“做一做”第2題） 全班同學(xué)動(dòng)手操作，1名同學(xué)到投影儀上操作。 （1）第1行擺5個(gè)△，在△下面擺○，△要比○多1個(gè)。第2行擺幾個(gè)○？ （2）第1行擺4朵紅花，擺的黃花比紅花少1朵，第2行擺幾朵黃花？ 二、運(yùn)用新知 教科書(shū)練習(xí)一第1～4題。 1．第1題：左圖是猴子多，右圖是骨頭多。（避免學(xué)生產(chǎn)生思維定勢(shì)） 2．第2題：學(xué)生觀察，看到公雞和鴨子雖然擺的一樣長(zhǎng)，但疏密不同，進(jìn)而判斷擺的密的鴨子的只數(shù)多些，而公雞只數(shù)少些。 3．第3題：學(xué)生在觀察到第一排蛋糕同樣多的基礎(chǔ)上，只需比較兩盒中的第二排。第二排多的就多些，反之，就少些。 4．第4題：此題是在同一排中比較多少，當(dāng)?shù)?次循環(huán)出現(xiàn)珠子時(shí)，只出現(xiàn)了一個(gè)黃色珠子，所以黃珠子多而紅珠子少。 三、總結(jié) 教師：今天我們學(xué)習(xí)了“比一比”，知道在比較時(shí)，一定要一個(gè)對(duì)著一個(gè)比，就會(huì)得到正確的結(jié)果。
