The classic Pink Tower (A040) consists of ten hand-painted wooden cubes graduating from 1 cm³ to 10 cm³, offering Children's House children a precise, self-correcting exploration of size in three dimensions. It anchors the sensorial curriculum by isolating the concept of dimension and building the mathematical mind's sensitivity to gradation. Having a well-crafted, true-to-spec set ensures the visual and muscular impressions children receive are accurate and lasting.
