There are 6 folded paper cranes, 3 large cranes and 3 small cranes. For each size of crane, they have a shape printed on them.

Each crane is folded and placed in an envelope and two symbols are drawn on the front of the envelope to identify its size and shape printed. One symbol identifies its size, and the other identifies its print shape (but in any order).

The envelope with a large crane and a triangle has the symbols “ @ , ♥ ” on it.

The envelope with a small crane and a circle has the symbols “ #, ¥ ” on it.

A third envelope with a crane has the symbols “ +, # ” on it.
