Transcript:What Is a Tangram Puzzle?Hey everyone, David Knupp here for About.com. When teaching children about geometry, tangrams are often used because they are fun and effective aides. A Tangram is a geometric puzzle which originated in China, and is made from three basic geometric shapes. They can be extremely challenging and fun. So today I’m going to show you what a Tangram is and how you can make one.
Tangrams are Made of the Same Puzzle Pieces> A Tangram is a simply a seven part geometric puzzle. It consists of five triangles, a square, and a parallelogram, called tans. They can be made from paper, cardboard, metal, or from many other different materials. The purpose of the Tangram is to organize it into different shapes. The rules for making a Tangram puzzle are simple, you must use all seven tans, they must all touch, and none can overlap. Here I have made a rabbit. Here is an example of a bird, and here I have made a candle. They possibilities are endless.
Make Your Own Tangram PuzzleIf you would like to make your own Tangram, you can simply download a premade template of one, and print it and cut along the lines. However, you can make one on your own set almost as easily. The first thing you should do, is to choose a square of material you would like your puzzle to be made from. I’m using an eight inch square of cardboard, but stiff paper works well too. Using a black marker, start by measuring out four equal sized squares onto the top side of your material. Now, continue measuring out squares down your material until you have a grid. Now, using a different color marker, draw the following lines across your grid. Now you can cut across the lines that are marked in the different color. Your now ready to start experimenting with different shapes and patterns.
