六年級上冊數(shù)學(xué)教案五單元5.3身高的情況北師大版教案：六年級上冊數(shù)學(xué)教案五單元5.3身高的情況北師大版一、教學(xué)內(nèi)容今天我們要學(xué)習(xí)的是北師大版六年級上冊數(shù)學(xué)第五單元的第三節(jié)內(nèi)容，主要討論身高的情況。我們將通過實際情境引入，讓學(xué)生了解和掌握單變量統(tǒng)計圖的應(yīng)用，能夠利用統(tǒng)計圖來表示和分析身高數(shù)據(jù)。二、教學(xué)目標1.學(xué)生能夠理解單變量統(tǒng)計圖的概念和作用。2.學(xué)生能夠通過單變量統(tǒng)計圖來分析和解釋身高數(shù)據(jù)。3.學(xué)生能夠運用所學(xué)的統(tǒng)計知識，解決實際生活中的身高問題。三、教學(xué)難點與重點1.教學(xué)難點：學(xué)生能夠正確地繪制單變量統(tǒng)計圖，并能夠根據(jù)圖表來分析和解釋身高數(shù)據(jù)。2.教學(xué)重點：學(xué)生能夠理解單變量統(tǒng)計圖的概念，掌握繪制和解讀統(tǒng)計圖的方法。四、教具與學(xué)具準備1.教具：黑板、粉筆、統(tǒng)計圖模板。2.學(xué)具：學(xué)生每人一份身高數(shù)據(jù)表格，一份統(tǒng)計圖繪制紙張。五、教學(xué)過程1.實踐情景引入：我們可以通過調(diào)查學(xué)生的身高來引入本節(jié)課的內(nèi)容?？梢宰屆總€學(xué)生測量自己的身高，并記錄下來。2.例題講解：我們可以利用學(xué)生提供的身高數(shù)據(jù)，來繪制單變量統(tǒng)計圖。我們可以將學(xué)生的身高數(shù)據(jù)整理成一張表格，然后根據(jù)表格來繪制條形統(tǒng)計圖或折線統(tǒng)計圖。3.隨堂練習(xí)：讓學(xué)生自己選擇一張身高數(shù)據(jù)表格，嘗試繪制單變量統(tǒng)計圖，并解讀圖表中的信息。六、板書設(shè)計1.單變量統(tǒng)計圖的概念和作用。2.繪制單變量統(tǒng)計圖的方法步驟。3.如何解讀單變量統(tǒng)計圖中的信息。七、作業(yè)設(shè)計身高數(shù)據(jù)表格：姓名身高（cm）150145160趙六155答案：根據(jù)身高數(shù)據(jù)表格，我們可以繪制一張條形統(tǒng)計圖或折線統(tǒng)計圖。通過圖表，我們可以看出的身高是150cm，的身高是145cm，的身高是160cm，趙六的身高是155cm。我們可以發(fā)現(xiàn)，的身高是最高的，的身高是最低的。通過解讀圖表，我們可以了解到學(xué)生的身高分布情況。八、課后反思及拓展延伸課后反思：通過本節(jié)課的教學(xué)，我覺得學(xué)生們對單變量統(tǒng)計圖的概念和作用有了初步的理解，大部分學(xué)生能夠掌握了繪制和解讀統(tǒng)計圖的方法。但是，還是有一部分學(xué)生在繪制統(tǒng)計圖時出現(xiàn)了一些錯誤，需要在今后的教學(xué)中多加指導(dǎo)和練習(xí)。拓展延伸：我們可以讓學(xué)生們進一步探索多變量統(tǒng)計圖的應(yīng)用，比如利用條形統(tǒng)計圖和折線統(tǒng)計圖來同時表示身高和體重數(shù)據(jù)，從而更加全面地了解和分析身高和體重之間的關(guān)系。重點和難點解析：1.單變量統(tǒng)計圖的概念和作用：這是學(xué)生首次接觸單變量統(tǒng)計圖，需要讓他們理解統(tǒng)計圖的目的是為了更直觀地展示數(shù)據(jù)，幫助分析數(shù)據(jù)背后的信息。單變量統(tǒng)計圖能夠清楚地表示出數(shù)量的多少，便于比較和分析。例如，在身高數(shù)據(jù)中，通過條形統(tǒng)計圖或折線統(tǒng)計圖，學(xué)生可以直觀地比較每個人的身高，找出最高和最矮的學(xué)生。2.繪制單變量統(tǒng)計圖的方法步驟：這是本次教學(xué)的難點之一。學(xué)生需要掌握如何根據(jù)數(shù)據(jù)繪制條形統(tǒng)計圖或折線統(tǒng)計圖。我會在課堂上詳細講解繪制步驟，并讓學(xué)生在實踐中繪制統(tǒng)計圖，以加深理解。例如，我們需要整理數(shù)據(jù)，將身高數(shù)據(jù)列成表格；然后，選擇合適的統(tǒng)計圖類型，根據(jù)數(shù)據(jù)繪制圖表；解讀圖表中的信息。3.解讀單變量統(tǒng)計圖中的信息：學(xué)生需要學(xué)會如何從統(tǒng)計圖中獲取有用的信息。我會通過具體的例子，讓學(xué)生學(xué)會如何分析統(tǒng)計圖，得出結(jié)論。例如，通過觀察身高統(tǒng)計圖，學(xué)生可以發(fā)現(xiàn)哪個學(xué)生的身高最高，哪個學(xué)生的身高最矮，以及身高分布的情況。4.學(xué)生的實際操作：在課堂上，我會讓學(xué)生親自動手繪制統(tǒng)計圖，并進行隨堂練習(xí)。這是教學(xué)的重點和難點之一，因為學(xué)生需要將理論知識應(yīng)用到實際操作中。我會提供指導(dǎo)和反饋，幫助學(xué)生克服困難，掌握繪制統(tǒng)計圖的技巧。5.作業(yè)設(shè)計：通過作業(yè)，學(xué)生可以進一步鞏固所學(xué)知識，并將所學(xué)應(yīng)用到實際問題中。在作業(yè)設(shè)計中，我會選擇與身高數(shù)據(jù)相關(guān)的題目，讓學(xué)生繪制統(tǒng)計圖，并解讀圖表中的信息。例如，讓學(xué)生根據(jù)給定的身高數(shù)據(jù)表格，繪制條形統(tǒng)計圖或折線統(tǒng)計圖，并回答相關(guān)問題。本節(jié)課程教學(xué)技巧和竅門：1.語言語調(diào)：我盡量使用生動、有趣的語言，以吸引學(xué)生的注意力。在講解單變量統(tǒng)計圖的概念和作用時，我以實際情境為例，讓學(xué)生更容易理解和接受。在講解繪制步驟時，我語速適中，確保學(xué)生能夠跟上我的講解，并能夠理解每一個步驟。2.時間分配：我合理分配了課堂時間，確保每個環(huán)節(jié)都有足夠的時間進行。例如，在講解單變量統(tǒng)計圖的概念和作用時，我花了大約10分鐘的時間進行講解；在講解繪制步驟時，我花了大約15分鐘的時間進行講解，并讓學(xué)生進行實踐操作；在解讀統(tǒng)計圖中的信息時，我花了大約10分鐘的時間進行講解，并讓學(xué)生進行隨堂練習(xí)。3.課堂提問：我在講解過程中適時提問，引導(dǎo)學(xué)生思考和參與。例如，在講解單變量統(tǒng)計圖的概念和作用時，我提問學(xué)生：“你們認為統(tǒng)計圖有什么作用？”在講解繪制步驟時，我提問學(xué)生：“你們知道如何繪制條形統(tǒng)計圖嗎？”通過提問，我可以了解學(xué)生的學(xué)習(xí)情況，并及時給予解答和指導(dǎo)。4.情景導(dǎo)入：我以實際情境引入本節(jié)課的內(nèi)容，讓學(xué)生更容易理解和接受。我讓學(xué)生測量自己的身高，并記錄下來，然后利用這些身高數(shù)據(jù)進行講解和繪制統(tǒng)計圖。這樣的情景導(dǎo)入使得學(xué)生對身高數(shù)據(jù)有了直觀的認識，從而更好地理解和掌握單變量統(tǒng)計圖的知識。教案反思：1.教學(xué)內(nèi)容的選?。何疫x擇了與學(xué)生生活密切相關(guān)的身高數(shù)據(jù)作為教學(xué)內(nèi)容，使得學(xué)生能夠更好地理解和接受。但在選取教學(xué)內(nèi)容時，我應(yīng)注意豐富性和多樣性，以滿足不同學(xué)生的學(xué)習(xí)需求。2.教學(xué)方法的運用：我運用了實際情境導(dǎo)入、講解、提問、實踐操作等多種教學(xué)方法，使得學(xué)生能夠從多個角度理解和掌握知識。但在運用教學(xué)方法時，我應(yīng)注意適時變換，以保持學(xué)生的學(xué)習(xí)興趣。3.課堂氛圍的營造：我在課堂上盡量營造輕松、愉快的學(xué)習(xí)氛圍，讓學(xué)生能夠放松心情，積極參與。但在營造課堂氛圍時，我應(yīng)注意把握度，避免過于輕松導(dǎo)致學(xué)生注意力不集中。課后提升：1.根據(jù)給定的身高數(shù)據(jù)表格，繪制一張條形統(tǒng)計圖和折線統(tǒng)計圖，并解讀圖表中的信息。身高數(shù)據(jù)表格：姓名身高（cm）150145160趙六155答案：根據(jù)身高數(shù)據(jù)表格，我們可以繪制一張條形統(tǒng)計圖和折線統(tǒng)計圖。條形統(tǒng)計圖：|························································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································
