Developed by a Florida Montessori teacher, the simple shapes in the L-Game provide a 2 piece puzzle that can be assembled 8 ways. This is a first exposure to control charts. Deceptively simple yet extremely useful in the classroom.

An amazing number of designs can be made with this simple puzzle. 

Chinese do tangrams like we do crossword puzzles.  The deluxe set comes in a tray with charts and directions.
