l尺子上每相鄰的兩條長刻度線之間的一大格的長度都是1厘米。師：我們大家現(xiàn)在一起用手比劃一下，1厘米多長。互相看一下，計(jì)住了嗎？閉上眼睛想一想，1厘米有多長。3、認(rèn)識幾厘米師：我們現(xiàn)在知道1厘米有多長了，那3厘米又有多長呢？師：同學(xué)們還能在尺子上找到其他3厘米的長度嗎？4、用厘米量師：剛才上課時(shí)，老師展示的2根線繩，到底哪一根長一點(diǎn)呢？現(xiàn)在，同學(xué)們先估計(jì)一下這兩根線繩各自多長，然后在測量比較一下，好嗎？師：結(jié)果是哪根線繩長一點(diǎn)呢？能說說你是怎么量的嗎？三、知識拓展1、師：老師這里有一把尺子，可是它斷了一節(jié)，沒有刻度“0”，只剩下刻度3到刻度10，那么這把尺子能不能用來量物體的長度?。客瑢W(xué)們能不能幫老師想一想辦法，好嗎？2、其他測量長度的工具（課件展示）

教后反思本節(jié)課給學(xué)生創(chuàng)設(shè)了良好的活動空間，把學(xué)生實(shí)際生活中聽說過的見到的平均分現(xiàn)象展示給學(xué)生看，把生活和數(shù)學(xué)聯(lián)系起來，在學(xué)生感受“同樣多”的基礎(chǔ)上概括出什么叫平均分。揭示平均分這一數(shù)學(xué)知識在生活中的應(yīng)用，之后突出了學(xué)生三次實(shí)際操作。第一次，小組同學(xué)互相分水果，重視學(xué)生分的結(jié)果。體會感受“平均分”的含義。第二次，重視分法：15個(gè)橘子平均分成5份。體現(xiàn)了學(xué)生對物品的不同分法，建立了平均分的概念。第三次，分礦泉水，通過份數(shù)變化，觀察分的就結(jié)果，深刻體會“平均分”，為認(rèn)識除法積累豐富的知識。為學(xué)生營造探索的空間。第二課時(shí)：平均分的認(rèn)識（二）教學(xué)內(nèi)容鞏固“平均分”。課本第15頁的例題3。教學(xué)目標(biāo)1.鞏固“平均分”的概念，知道平均分就是每一份分得結(jié)果同樣多。
