project style -- Tangram updated lol

Tangram as a well known puzzle game. It is a dissection puzzle consisting of seven flat shapes, called tans, which are put together to form shapes. The objective of the puzzle is to form a specific shape (given only an outline or silhouette) using all seven pieces, which may not overlap. It is reputed to have been invented in China during the Song Dynasty, and then carried over to Europe by trading ships in the early 19th century. It became very popular in Europe for a time then, and then again during World War I. It is one of the most popular dissection puzzles in the world. A Chinese psychologist has termed the tangram "the earliest psychological test in the world", albeit one made for entertainment rather than analysis.

Trader, in 1815. When it docked in Canton, the captain was given a pair of Sang-Hsia-koi's (author) Tangram books from 1815. They were then brought with the ship to Philadelphia, where it docked in February 1816. The first Tangram book to be published in America was based on the pair brought by Donnaldson.

The puzzle was originally popularized by The Eighth Book Of Tan, a fictitious history of Tangram, which claimed that the game was invented 4,000 years prior by a god named Tan. The book included 700 shapes, some of which are possible to solve.

Tangrams for kids: An overlooked learning tool?

http://www.parentingscience.com/tangrams-for-kids.html

I useTangram in my animation project: use Tangram as the main character, "play" tangram as a storyline. Combine physical play and fun animation program to help kids learn.

Physical play:

Whatever is structure or unstructured play, there are many advantage or disadvantage during the play.

Kids play game, training they brain, develop their various skill, improve communication abilities. However, there still has many downsides. As the parent, the best course of actin is to discuss safe play with their kids, keep a close eye on them when they're playing and stop any activity that could lead to a dangers situation immediately. I was think that if there is a program which combine physical activity and also allow them to STAY SAFE.

by the way...

Some questions that still exist:

• Can tangrams be used with all grade levels including high school?
• Are mathematicians still exploring what tangrams have to offer?
• Are there any disadvantages to using tangrams?

When it comes to tangrams, the challenge is to arrange the pieces to form additional shapes. The seven pieces can be arranged to make anything form a rabbit, to the alphabet, to a person. 

"The tangram is the opposite of a jigsaw puzzle. Instead of fitting the pieces together in only one way, the seven tangram pieces can be arranged to make a great number of different figures" Bohning, G., et al..

Interactivity is a mutual action between the learner, learning system, and learning material. Learners will be faster to learn, and have better attitudes toward learning when using interactive animation especially if the other techniques like audio and video are used.
