“根据方向和距离确定物体的位置”是小学数学高年级段“图形与几何”中方向与位置方面的学习内容。通过本节课的研究,教师可以发现影响确定物体位置的因素——方向和距离,只有将方向和距离两者结合起来,才能确定物体的准确位置。这节课与前面的“根据行数和列数(或”数对“)确定物体的位置”学习内容对应起来,将方向与位置 “Determine the position of the object according to the direction and distance ” is the learning content of the direction and position in the upper grades of elementary mathematics “Graphics and Geometry ”. Through the research in this lesson, teachers can find out the factors that affect the position of the object - the direction and the distance. Only by combining the direction and the distance can the teacher determine the exact position of the object. This lesson is similar to the previous section “Determining the position of an object based on the number of rows and columns (or” pairs “) ” Learning content,
