There is something so beautiful about simple wood toys. This one is a great learning tool for kids as it brings math into a world of shapes and colors rather than numbers. A wooden base has four square holes to be filled with square fractions and teaches children about fractions and problem solving.

Made by Plan Toys, this one comes in its original box and we think it is of recent vintage age (70s-80s). Made of replenishable rubber wood and non-toxic colored.
