five. In each group one student selects any 
three shapes and puts them together. The 
student, then describes the sequence of 
construction and the other students have to 
build the same without seeing the original 
one. Let children take turns and play the 
game in the group.
Example
The cylinder is on top of the cuboid. The cone is on top 
of the cylinder.
