二元一次方程組教案教學設計
1、問題1的設計基于學生已有的一元一次方程的知識，學生獨立思考問題，同學會考慮到題中涉及到等量關系，從中抽象出一元一次方程模型；同學可能想不到用方程的方法解決，可以由組長帶領進行討論探究.2、問題2的設計為了引出二元一次方程，但由于同學的知識有限，可能有個別同學會設兩個未知數(shù)，列出二元一次方程；如果沒有生列二元一次方程，教師可引導學生分析題目中有兩個未知量，我們可設兩個未知數(shù)列方程，再次從中抽象出方程模型.根據(jù)方程特點讓生給方程起名，提高學生學習興趣.3、定義的歸納，先請同學們觀察所列的方程，找出它們的共同點，并用自己的語言描述，組內(nèi)交流看法；如果學生概括的不完善，請其他同學補充. 交流完善給出定義，教師規(guī)范定義.
