学习目标1.通过活动,引导学生对四五年级找规律的相关知识进行串联和建构。2.让学生在动手实践的过程中,经历观察——猜想——验证的探究过程,发展学生归纳和初步演绎的思维能力。3.感受数学无处不在,体验数学规律的美妙,在规律的拓展运用中获得“活动学习”的快乐。教学准备线绳、玩具拉面、钉子板等。教学过程一、巧设疑问,激发兴趣师:(出示几根线绳)同学们,你们看老师手里拿的是什么?师:这些是在生活中常用的线绳。今天,我们将要用这些线
Learning Objectives 1. Through activities, to guide students to find the law of the fourth and fifth grade related knowledge in series and construction. 2. Let students in the process of hands-on experience, through the observation - guess - verification of the inquiry process, the development of students induction and initial interpretation of thinking skills. 3. Feel mathematics everywhere, to experience the beauty of mathematical laws, in the use of the law to expand the use of “activity learning” happiness. Teaching preparation for rope, toy ramen, nails board and so on. Teaching process First, the clever question, to stimulate interest Teacher: (show a few lines of rope) Students, you see what the teacher’s hand? Teacher: These are commonly used in life line. Today, we will use these lines
