一、教材及学情分析本课内容为西南师范大学出版社出版的《九年义务教育课程——数学第八册》第三单元中的《确定位置》。在学习本节课的内容之前,孩子们已经在第一学段学习了前后、上下、左右等表示物体具体位置的知识。本节课的学习则是前面内容的发展,让孩子们在具体的情境中,探索确定位置的方法,说出某一物体的位置,并能在方格纸上用“数对”确定位置。这些知识的学习对提高孩子的空间观念,帮助认识周围的环境,都有较大的作用。为今后学习直角坐标系的知识作铺垫。
First, the textbook and academic analysis This course content for Southwest China Normal University Press, “Nine-year compulsory education curriculum - mathematics eighth volume” in the third unit “to determine the location.” Before studying the content of this lesson, the children have learned about the specific location of objects before, after, around, around, etc. in the first semester. This lesson is about the development of the previous content, so that children in specific situations, to explore ways to determine the location, say an object position, and can be used on the grid paper position. This knowledge of learning to improve children’s space concept, helping to understand the surrounding environment, have a greater role. For future learning Cartesian coordinate knowledge pave the way.
