个小正方体组合的形状，并画出草图；培养学生的立体感。重点难点：能正确识别从不同方向观察到的立体图形的形状。教具准备：小立方体学生用，大立方体教师用教学过程：一、新课从不同方向正面、侧面、上面观察立体图形5 个小正方体组合的形状。1、拿出 5 个小正方体，摆成下面形状观察由 5 个小正方体搭成的立体图形的形状。想一想，从正面看是什么形状，从侧面、上面看呢？又是什么形状？画一画，分别画出从正面、侧面、上面观察到的图形。|精.|品.|可.|编.|辑.|学.|习.|资.|料.*|*|*|*|欢.|迎.|下.|载.第 2 页，共 4 页文档编码:CQ5V5W1R9N8 HV4W4T8P3V1 ZA4X4R2S9A6文档编码:CQ5V5W1R9N8 HV4W4T8P3V1

个小正方体，摆成下面形状1从不同方向再观察，想象它的形状。2画一画，学生单独画出从正面、侧面、上面观察到的和想象的立体图形。3展示画出的图形。师在黑板上画出图形。4师：从三个不同方向观察，为什么只看到3 个正方形或 4 个正方形？你想过为什么吗？这个物体不是由5 个小正方体搭成的吗？应该看到5 个才对呀，还有一个到哪去了呢？生：很容易地指出来被遮挡住了。师：虽然看不见，但它仍然是组成这个立体图形的一局部。请分别指出从三个不同方向正面、侧面、上面看不见的是哪一个？从正面、右面看较难，因为有被遮住的，要注意辅导学困生3、练一练P78练一练 1：学生独立完成，集体订正，对于有困难的学生可借助学具实际摆一摆，看一看。4、摆一摆，画一画学生用 5
