    二、學習新知1.正方形的定義在這一環(huán)節(jié)中,學生很容易犯的一個錯誤就是條件重復。這時我會引導學生從畫圖入手,提示他們:你能不能減少條件畫出正方形呢?這一環(huán)節(jié)中我的觀點是正方形的定義不是唯一的。我們可以從不同的角度來總結,只要合理就加以肯定。比如當學生總結出:四個角都是直角,四條邊都相等的四邊形是正方形。這時可以提醒學生是不是一定要四條邊都相等,減少邊的條數(shù)可以畫出來嗎?角的個數(shù)可以減少嗎?鼓勵學生動手試一試。通過動手畫圖可以很容易的得到正方形的一個定義:三個角都是直角,一組鄰邊都相等的四邊形是正方形。通過小組討論的形式來完成這一環(huán)節(jié)的設置。鼓勵學生利用現(xiàn)有的材料繼續(xù)構造正方形。從另一個角度總結正方形的定義。
