上数学课了,陈老师打开电脑,出示了下面几个立体图形,对同学们说:“这4个物体都是用同样的小方块搭成的,第几个物体从前面、上面、右面看,看到的形状都相同?”爱动脑筋的聪聪首先发言,他说:“我按‘观察——画图——比较’的思路找答案。观察第(1)个物体,从前面看,可以看到下层的2个正方形和上层左边的1个正方形,所以看到的形状是 On the math class, Chen opened the computer, produced the following three-dimensional graphics, to the students said: ”These four objects are made of the same small square, the first few objects from the front, above, right See, to see the shape is the same? “” Brainstorming Congcong first spoke, he said: “I press the” observation - drawing - comparison ’train of thought to find the answer.Observation of the first (1) Front view, you can see the lower two squares and the upper left one square, so see the shape
