【教学内容】人教版五年级上册第19、20页。【课前思考】本课主要学习能用数对表示具体情境中物体的位置,以及能在方格纸上用数对确定物体的位置。学生在之前已经学习过用“第几组第几个”的方式来描述实际情境中物体的位置,并且在生活中也有许多类似的经验,但是学生对物体位置的描述还没有形成特定的规范。因此,在教学“用数对确定位置”时应充分利用这些经验和知识为学生提供探究的空间,让学生通过充分体验、深入
【Teaching content】 PEP fifth grade Volume 19,20 pages. [Thinking Before Class] This lesson focuses on the ability to use pairs to represent the location of an object in a specific situation and to determine the position of an object on a piece of graph paper. Students have previously learned to describe the location of objects in real situations by using “how many”, and they have many similar experiences in their lives, but the students’ description of the object’s location has not yet become specific specification. Therefore, in the teaching of “the number of pairs to determine the position,” should make full use of these experiences and knowledge to provide students with space for inquiry, so that students through the full experience, in-depth
