TANGRAMS - An Introduction


The origins of the tangram puzzle are not known with any certainty, but the idea is thought to have originated in China about 250 years ago.
You need a set of tangram pieces to work on these puzzles.

To make a set of tangram pieces
Cut out a square piece of card.
About 6 or 8 cm square is a good size.
Lightly mark a 4 by 4 grid of squares on it, as shown in the diagram on the right, to act as guide-lines.

This should make the 7 pieces of the tangram as shown below.
