A "Graded Tower" for kids, often referred to as a "stacking tower" or "tower of cubes," is a foundational developmental toy rooted in early childhood education principles, most notably those of Maria Montessori. The toy consists of a set of blocks or cubes of the same color, but each one is a different size, increasing or decreasing incrementally. The Graded Tower typically includes ten cubes or blocks, all of the same solid color (often pink or brown in the Montessori tradition), ranging from a very small size to a much larger one. The blocks are precisely cut to create a visually striking and orderly progression in size.
