Academic Tangrams!


It's time to review for a test! Let's play with tangrams!

What are Tangrams?

Tangram is an ancient Chinese game that is also known as "the wisdom puzzle." The objective of this puzzle is to fit together the seven pieces, called tans, (shown below) so that they form a given shape.

Many shapes are possible. Several possibilities are shown below:

What are the rules for using the pieces to form these shapes? They are quite simple. You must use all seven tans, and they must lay flat. They must touch, and none may overlap. It can be harder than it appears and can be a lot of fun. We will use this ancient game to help us review!

How to Play

  1. The class should split into four groups.
  2. With each question, a representative of the team is selected to write on the board. Each team's representative goes to the board.
  3. A question is asked.
  4. All team members can contribute by suggesting to the representative at the board what to write.
  5. When a representative is done, he/she yells "done" and sits down.
  6. The remaining groups continue to work on the problem until all groups complete the problem or time is called.
  7. The group that finishes first with the correct answer is awarded a point and 15 seconds to work on the tangram.
  8. A team is awarded 3 points when they place all of the pieces of the tangram correctly to create the desired picture within their 15 second allotment.

Using the Web Tangram board

The Tangrams are presented in a Java applet.

Adaptations

If you do not have online access in your classroom, this game can be modified for classroom review. The class is still split into teams with questions being answered in the manner given above. The teams begin each round of the game without any tans. When a team gives the correct answer, they are awarded one tan. The first team to collect all 7 tans and construct the desired shape wins 3 points. For a handout of several possible configurations for the tangram shapes, click here.
