Tangram Set

Most of us have had the pleasure of forming different patterns with a classic Tangram set, reenforcing the mathematical relationships the seven pieces have with each other. You can now make an origami version of this classic puzzle, with each piece formed from the same sized square. There are some tricky reference points, giving this model a "low intermediate" level designation. Diagrams for this can be found in the book Explore Math with Origami:

Seven sheets of kami will be needed (6"/15cm) for a complete set of pieces.
