【教学内容】人教版《数学》四年级上册64~65页。【设计理念】垂直与平行在生活中有着广泛的应用,学生头脑中已经积累了表象,因此,教学设计要唤起学生的生活经验,感知生活中的垂直与平行现象,通过观察、讨论等活动让学生感知、理解、发现、认识,从而使学生的空间想象力得到进一步的发展。【背景分析】本课教材是在学生学习了直线及角的认识的基础上教学的,是认识平行四边形和梯形的基础。垂直与平行是同一平面内两条直线的两种特殊的位置关
Teaching content】 【PEP “Math” fourth grade on the book 64 ~ 65 pages. 【Design Concept】 Vertical and parallel have a wide range of applications in life. Students have already accumulated the appearance in their minds. Therefore, instructional design should arouse students’ life experience and sense the vertical and parallel phenomena in life. Through observation and discussion activities, Students perceive, understand, discover and recognize, so as to further develop students’ spatial imagination. Background Analysis This course is based on the students’ understanding of the straight line and angle of teaching, is the basis for understanding the parallelogram and trapezoid. Vertical and parallel are two special positions of two straight lines in the same plane
