Material name: Pink Tower – Montessori Pink Tower
Area: Sensorial
Purpose & developmental benefits:
The Pink Tower is a foundational Montessori sensorial material that helps children recognize and distinguish size in three dimensions (height, width, and depth) by stacking wooden cubes from largest to smallest. As children build the tower, they observe, compare, and self-correct to create proper order. This process supports the development of logical thinking, concentration, and a strong sense of order.
Skills children develop:
-
Recognize differences in size across three dimensions
-
Arrange objects in order from large → small or small → large
-
Develop hand–eye coordination, fine motor skills, and gross motor control when carrying and placing the cubes
-
Strengthen observation, estimation, and self-correction skills
-
Build concentration, persistence, and sequential work habits
-
Enrich language: big–small, large–tiny, tall–short, increasing–decreasing
-
Prepare logical thinking and geometric foundations (cube form, volume)
Recommended age: 2.5–6 years old (Casa)
Typically introduced early, once the child is comfortable working on a floor mat.
Materials & components:
-
A set of 10 wooden cubes with gradually increasing size (from smallest to largest), each edge increasing evenly (commonly from 1 cm to 10 cm)
-
Uniform pink color to isolate the concept of size
-
Natural wood with smooth surfaces and rounded edges for safety
-
Proportions standardized according to Montessori principles
Control of error:
When stacked incorrectly, the tower appears uneven or loses its harmonious “stepped” form, allowing the child to self-correct naturally.
Use in the classroom / at home:
Used on a mat in the Sensorial area. Children learn to carry each cube with both hands, stack the tower from largest at the bottom to smallest at the top, then observe and adjust independently. Extensions may include building the cubes horizontally to form a “stair,” combining with the Brown Stair for size comparison, or language games (e.g., “find the third largest cube” or “the second smallest cube”). At home, place the tower on a low shelf and allow the child to work in a spacious, quiet area to ensure safety and sustained concentration.
