Tangrams

The tangram 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 in outline or silhouette) using all seven pieces, which may not overlap. They can be help for developing:
  • Problem Solving
  • Shape Concepts
  • Perceiving Spatial Relationships
  • Visual Discrimination
  • Visual Memory
  • Visual Thinking
  • Perceptual / Visual Information Processing
  • Eye-Hand Coordination
  • Fine Motor Coordination

Kids love trying to solve tangram puzzles and if you don't have any in your classroom, here are some fabulous online versions you can use instead.

Cyberchase Tangrams is a site that offers both hints and the option to turn on an outline of the puzzle in case you need a little help.



Tangram House has many puzzles and allows you to shift all of the tans left or right, up or down.


Online Tangrams allows you to chane the color of your tans.


Flash Tangram Puzzle has options for resetting and solving as well as lots of puzzles to try out.

 
 
Once they've spent a bunch of time solving tangram puzzles, your students will probably want to create their own.
 
Virtual Tangrams page allows you to create your own tangram creations as well as change the color of your tans.
 
 


 Mathwire has a great Tangram Lesson complete with literature links, patterns for creating your own paper tangrams, and much more.
