  7.学画平行线

  (1)自学画法,独立试画。

  (2)说一说你是怎样画的。

  (3)试用最佳方法画一画。

  三、巩固练习

  1.判断

  (1)永不相交的两条直线是平行线。

  (2)相交的两条直线是平行线。

  (3)的两组对边互相平行。

  (4)线平行无论怎么延长也不相交。

  (5)相邻的两边是平行的。

  2.游戏:找出图中藏着的平行线。

  四、作业:

  画平行线;找一找:生活中有哪些平行线?

  教学反思:

  学生动手画线、观察认识平行线,完善平行线的概念,会画平行线,实际测量平行线间距离相等,教师在测量的过程中应放手让学生操作。
