數學閱讀理解 • 進行數學閱讀理解教學設計 舉教科書例子進行數學閱讀理解教學設計 • 實作(Polya怎樣解題 ) 1.瞭解題意 2.擬訂計畫 3.執行計畫 4.反省檢討
姐姐和安琪各有2560元和1480元， 題目1 姐姐用了174元買貼紙後，還比安琪多幾元？ (用一個算式做做看) 了解題意 題目提到什麼? 答案 姐姐 安琪 貼紙 答案 姐姐和安琪各有2560元和1480元， 姐姐用了174元買貼紙。 題目說了什麼事? 題目在問什麼事? 答案 買貼紙後，姐姐還比安琪多幾元？
擬訂計畫 圖 示
策略 (？) = 2560 - 174 先算 (？) 1480 - ( ? ) 再算 =
執行計畫 想想看 用一個算式該怎麼算呢? 可以從已經知道的事來算哦! 解題 174 - - 2560 = 1480 (？) 答案 姐姐比安琪多906元
反省檢討 將答案帶到式子中看看對不對？ 檢查 2560 + = 174 906 + 1480 ，表示算對了
想一想 2560－174 － 1480 ＝ 906和 有什麼關係? = 2560 + 1480 + 174 906
