数学活动—我的柜子

我们每个小朋友都有自己的书柜,但是你们能准确的告诉我,你们的书柜是哪一格吗?
今天我们来学习用坐标的方法来准确描述我们柜子的位置。
http://s7/mw690/003VSf6jzy7cfneaE74c6&690看老师这张图上都画了什么?这些格子是什么意思?
图纸上一共有多少格?我们班有多少个小朋友?
这些格子与我们的柜子里的格子有什么关系?

这些格子横排叫行,竖排叫列。

这些格子横排叫行,竖排叫列。
通常我们表达一个物品的位置,可以表达它在第几行第几列,表示为(*,#)
如小兔在第一行,第二列,可表示为(1,2)

请小朋友们根据这样的方法找出其它物品的位置,即表达方式。
