找规律初中数学（Find the law of junior high school mathematics） Two grade math lesson plan - circular permutation rule Source: network 2009-09-04 22:57:05 [label: Grade Two Lesson Plan math] Olympiad essence information free subscription First, the teaching content Find the law version of the compulsory education curriculum standard experimental textbook of mathematics teaching the second grade II P115 Two, teaching preparation A courseware, pictures, a number of Three, teaching objectives and Strategies Teaching target: 1, through observation, speculation, experiment, reasoning and other learning activities, found that the pattern of cyclic arrangement. 2, the process of finding, analyzing, and finding the cyclic arrangement of graphs, knowing that the arrangement of things in life has the law of cyclic arrangement. 3, through learning activities to develop students imagination, cultivate students innovative consciousness. 4, feel the value of mathematics, discover and appreciate the consciousness of mathematical beauty. Circular permutation rule is to find the law students the first grade II (or repeated graphics increases (decreases) of the law on the basis of the continuity of learning). Its not easy for grade two students to have a thorough understanding of the patterns of cyclic permutation in graphs. Therefore, I proceed from the actual situation of students and make proper treatment of them. First of all, real life situations into contact students, find the prototype from the life cycle, the students are familiar with the running, shooting, jumping and other activities, to present the students of law, let the students in the observation cycle of the initial perception of the forming process. Secondly, the topic map presentation by dynamic contact type, the students are familiar with the long jump event, according to a certain order, let the students feel the formation process of cycle; again, the law has diverse forms, from the matrix extension line shape, special s
