Building in the mirror was easy and fast for some.
For others the projects came out mirrored.
Pairs tried out the communication project with the Mystery object pieces
by sitting back to back. Taking turns, a piece is chosen and orally
described.
Then instructions are given as to how to place it. The
other student follows the instructions.
The next piece and placement are chosen by the other student.
They alternate giving oral instructions until all the pieces are placed.
Then look to see how closely alike the objects are.
