《间隔排列(探索规律)》是苏教版三年级上册的综合与实践内容,对于规律的表述,教材没有直接给出,而是让学生自己归纳和表达,让学生经历间隔排列的两种物体个数之间的关系的探索过程,体会观察、比较、归纳是寻找和发现规律的基本方法。初步体会其中蕴含的简单数学规律,由此增强学生探索、研究问题的兴趣和能力。让学生自主找出这个规律,并应用这个规律解决相关的实际问题,建立了学生学好数学的自信心,体验了学习的 “Arrangement of intervals (exploration of law)” is the third edition of the Sujiao version of the comprehensive and practical content, the law of the presentation, the textbook is not given directly, but let students themselves induction and expression, so that students experience two kinds of spaced objects The relationship between the number of exploration process, experience observation, comparison, induction is the basic method to find and find the law. Preliminary understanding of the simple mathematical law contained therein, thereby enhancing students to explore, research interest and ability of the problem. Allow students to find out this rule autonomously, and apply this law to solve the practical problems related to the establishment of students to learn mathematics self-confidence, experience the learning
