Plan Toy Stacking Ring honors a tradition with this beautiful version of the classic stacking rings. This "old world" styled rendition reminds us that there is virtue in simplicity. Stack the colored rings in any order on the wooden pole. The child discovers basic math concepts and learns about color, counting and size while playing. The pole will collapse if the rings aren't on the pole. Always a favorite, especially of grandparents, it has a warm, well-earned place in everyone's heart.
