11、教科書 / 人民教育出版社 2014 年版內(nèi)容來源： 小學(xué)四年級數(shù)學(xué)（上冊） 第四單元主題：三位數(shù)乘兩位數(shù)的筆算方法課時：共 2 課時，第 1 課時授課對象 ：四年級學(xué)生設(shè)計者：目標(biāo)確定的依據(jù)1. 基于課程標(biāo)準(zhǔn)的思考數(shù)學(xué)課程標(biāo)準(zhǔn)（ 2011 年版）有關(guān)本課的要求是：教學(xué)時，應(yīng)通過解決實際問題進一步培養(yǎng)學(xué)生的數(shù)感， 增進學(xué)生對運算意義的理解； 能筆算三位數(shù)乘兩位數(shù)的乘法。2. 教材分析三位數(shù)乘兩位數(shù)的筆算方法 是四年級上冊第三單元的內(nèi)容。 學(xué)生在三年級下冊已經(jīng)學(xué)過三位數(shù)乘一位數(shù)、 兩位數(shù)乘兩位數(shù)的乘法筆算。 本節(jié)課在此基礎(chǔ)上教學(xué)三位數(shù)乘兩位數(shù)筆算的基本方法。 三年級時，學(xué)生已經(jīng)掌握了三位數(shù)乘一位

12、數(shù)與兩位數(shù)乘兩位數(shù)筆算， 因此，對算理和算法的理解和探索并不會感到困難。但是，由于因數(shù)數(shù)位的增加， 計算的難度也會相應(yīng)的增加， 計算中就會出現(xiàn)各種不同的情況，因此，這一課的學(xué)習(xí)對學(xué)生來說也是非常必要的。 學(xué)習(xí)這部分內(nèi)容，有利于學(xué)生完整地掌握整數(shù)乘法的計算方法， 并為以后進一步學(xué)習(xí)小數(shù)乘法打好基礎(chǔ)。教材提供的情景中， 讓學(xué)生建立速度的概念， 經(jīng)歷從實際問題中抽象出時間、路程和速度的關(guān)系，并應(yīng)用這種關(guān)系去解決問題。目標(biāo)根據(jù)以上分析以及新課標(biāo)提出的要求： 要讓學(xué)生在獲得新知的同時， 在情感態(tài)度價值觀等方面都能得到進一步發(fā)展和培養(yǎng)，我制定了以下的教學(xué)目標(biāo)1、知識技能目標(biāo)：讓學(xué)生經(jīng)歷探索三位數(shù)乘兩位數(shù)計

13、算方法的過程，掌握三位數(shù)乘兩位數(shù)的筆算方法，能正確地進行計算。2、情感與態(tài)度目標(biāo)：讓學(xué)生獲得運用已有知識解決新的計算問題的體會，體驗成功的愉悅，進一步樹立學(xué)習(xí)數(shù)學(xué)的自信心。3、能力目標(biāo)：使學(xué)生在探索計算方法和解決實際問題的過程中體會新舊知識的聯(lián)系，能主動總結(jié)、歸納三位數(shù)乘以兩位數(shù)的筆算方法，培養(yǎng)類比及分析，概括能力，發(fā)展應(yīng)用意識。評價任務(wù)1. 在小組內(nèi)互相說一說，三位數(shù)乘兩位數(shù)的筆算方法。2. 對同學(xué)的板演情況進行正確判斷，并能獨立完成課堂練習(xí)題。教學(xué)過程regulations raise theoverall levelof ecologi cal civilization construc
