一、教材分析《辨认方向》是北师大版数学教材第四册第三单元“方向与路线”第一节的内容。辨认东北、西北、东南、西南,是在学生已经学会辨认东、南、西、北四个方向的基初上进行教学的。能正确辨认现实生活中的方向,用东、南、西、北、东北、西北、东南、西南描绘物体所在的方向,对于二年级的小学生来说具有一定难度。因此,在教学时,教师一定要借助学生已有的知识水平和生活经验创设现实的活动情境,增加参与、体验的机会,让所有的学生都能积极参与到数学活动中去 First, the textbook analysis “Identify the direction of” is the third unit of the fourth division of Beijing Normal University mathematics textbook “direction and route ” the first section. Identifying the northeast, northwest, southeast and southwest is teaching the students first to learn to identify the four directions of East, South, West and North. Can correctly identify the direction of real life, East, South, West, North, Northeast, Northwest, Southeast, Southwest depicts the direction of the object, for the second grade pupils have a certain degree of difficulty. Therefore, in teaching, teachers must use the existing knowledge and experience of students to create realistic scenarios and increase the opportunities for participation and experience so that all students can actively participate in math activities
