2017年暑假作業(yè)答案匯總 2017年各年級(jí)暑假作業(yè)答案

孩子寫(xiě)作業(yè)的壞習(xí)慣

現(xiàn)象一不知道著急：動(dòng)作拖拉

很多孩子平時(shí)寫(xiě)作業(yè)的時(shí)候就喜歡拖，每次都要磨蹭到晚上8點(diǎn)半，甚至是9點(diǎn)以后才開(kāi)始寫(xiě)，上學(xué)尚是如此，假期就更加更加喜歡拖了。

經(jīng)常會(huì)說(shuō)明天再寫(xiě)吧，等到了明天，又不想寫(xiě)再推遲，直到開(kāi)學(xué)前幾天，才開(kāi)始夜以繼日的趕。

孩子的小心思：假期這么長(zhǎng)，我先玩幾天再寫(xiě)也來(lái)得及!大不了最后幾天多寫(xiě)點(diǎn)。

2017年暑假作業(yè)答案匯總 2017年各年級(jí)暑假作業(yè)答案

現(xiàn)象二人在心不在：注意力不集中

好不容易下定決心寫(xiě)了，可是心思完全不在作業(yè)上，最多堅(jiān)持15—20分鐘，然后就一會(huì)出去倒杯水，一會(huì)去上個(gè)廁所;家里來(lái)客人了，一定要出去看看，不然就放個(gè)手機(jī)在旁邊，拍個(gè)自拍發(fā)個(gè)朋友圈……完全沒(méi)有時(shí)間概念，能2個(gè)小時(shí)完成的作業(yè)，硬是被拖到了5個(gè)小時(shí)。

孩子的小心思：寫(xiě)作業(yè)好無(wú)聊啊~好煩啊~我把這道題寫(xiě)完，玩一會(huì)兒游戲，再寫(xiě)吧。這樣才有動(dòng)力。

2017年暑假作業(yè)答案匯總 2017年各年級(jí)暑假作業(yè)答案

現(xiàn)象三質(zhì)、量難兼顧：答題不走心

平時(shí)寫(xiě)作業(yè)的時(shí)候，孩子不敢怠慢，因?yàn)閷?xiě)不好第二天會(huì)被老師批評(píng)?？墒罴俨灰粯影。蠋煵粫?huì)每天都盯著你作業(yè)質(zhì)量，于是孩子答題非常不規(guī)范：不寫(xiě)題號(hào);數(shù)學(xué)應(yīng)用題也不寫(xiě)“解”，得出結(jié)論后也不寫(xiě)“答”;格式混亂，解題過(guò)程跟草稿紙上的演算一樣龍飛鳳舞。

還有的孩子對(duì)橡皮或者涂改液有嚴(yán)重的依賴，稍微有一點(diǎn)點(diǎn)小瑕疵，就擦掉重寫(xiě)，不僅效率低下，書(shū)面不整潔。

家長(zhǎng)怎么教育孩子寫(xiě)作業(yè)

關(guān)于作業(yè)，一定要告訴孩子的話作業(yè)每個(gè)人都有，并不是老師和家長(zhǎng)故意針對(duì)你。所以，不要抱怨，不要覺(jué)得不公平，反正學(xué)得多學(xué)得少都是你自己的。不管怎么樣，你始終都要完成，每天按時(shí)完成了再放心地玩還是千方百計(jì)拖到最后，玩的時(shí)候還要惦記著作業(yè)，全憑你自己選擇。作業(yè)就是這樣，你難的時(shí)候別人也難，你簡(jiǎn)單的時(shí)候別人也簡(jiǎn)單，但不是每個(gè)人都可以做到思考全面，認(rèn)真仔細(xì)的，差距就在這里。每一道你做過(guò)的題，只要認(rèn)真思考了，都是你新的知識(shí)和經(jīng)驗(yàn)。就像人生一樣，經(jīng)歷過(guò)的，就都是你獨(dú)一無(wú)二的財(cái)富!
