六年级数学教材中的“抽屉原理”是体现建模思想的一个典型课例,教学中应该采用直观方式,重点引导学生经历“数学证明”的过程,从而完成对“抽屉原理”的探究。一、游戏激趣初步体验上课之前,我先让学生玩抢椅子游戏。游戏要求是:这里有4把椅子,请五位同学到前面来,老师一说开始,大家都要坐到椅子上。在游戏中,学生亲身感受到不管怎么坐,总有一把椅子 Sixth grade mathematics textbook “drawer principle ” is a typical example of modeling thought, teaching should adopt an intuitive way, focusing on guiding students to experience “mathematical proof ” process, thus completing the “drawer principle ”Inquiry. First, the game interesting initial experience before class, I let students play grab chair game. Game requirements are: There are 4 chairs, please come to the front of five students, the teacher said the beginning, we have to sit on the chair.
