This solid hardwood Classification Learning Center consists of a 5 compartment sorting box with 10 category wood tiles and 100 wood object tiles to sort by class. The child can start with one or two categories and work up to sorting 5 categories at a time. Answers are easily checked by removing sorted tiles from each compartment and comparing them to the category guide card. An additional, unlimited number of object tiles can easily be made by using cut-outs of objects from newspapers, magazines, coloring books, etc.
