以情激趣,以趣质疑——《乘法分配律》教学案例（To love interest, interest in the question -- a teaching case of distributive law multiplication） To love interest, with interesting questions -- teaching case of distributive law of multiplication Tongzhou District Yu Bridge Primary School, Beijing, Han Hongtao The new curriculum emphasizes starting from the existing life experiences of the students, let students experience the process of practical problems into mathematical model and interpretation and application, and enable students to gain mathematical understanding at the same time, progress and development in thinking ability. Based on the study and understanding of the new curriculum standard, I do the following exploration on the practical concept of the multiplication distribution law. I. Analysis of teaching materials The exploration process of this class is to let students find problems in the course of activities, make assumptions, verify examples and establish models. The emphasis of teaching is on the guidance of the exploration process. Because the students have some basic exploration, so the teaching activities, let students pay attention to their own to explore, teacher guidance, in the key role play point. Embody the teaching principle of student as the main body and teacher as the leading part in the classroom teaching, and pay attention to the cultivation of students various abilities in the course of activities. Two. Student analysis The students active thinking, extensive knowledge, most of the students interest in learning mathematics is very strong, in the mathematical sense of exploration is also very strong, and can contact the actual use of knowledge to solve mathematics problems in life. Students have the habit of self exploration, solidarity, cooperation and communication with others. But individual students have poor foundation and bad study habits. Three, teaching objectives: Knowledge target: By means of observation, analogy, induction, verification and applica
