Our 1st and 2nd graders are wrapping up a unit on visual-spatial reasoning with a lesson on tangrams--an ancient geometrical puzzle and storytelling tool comprised of 7 pieces. The video below introduces their origin.
OK, so that's not the actual origin of trangrams, but it is an excellent introduction. In class we manipulated physical tangrams, but there are some nice websites with tangram activities too:
Matter - Online Tangram Puzzles
PBS Kids - Sagwa Tangram Games
Think a 7-piece puzzle sounds too easy? Think again!
