The Brown Stair (Clear Lacquer)

Graded Cubes Series is an important educational tool for schools, kindergartens, and learning centers. It shows children the change in width while the length remains constant, through precise gradations from 1 × 1 × 20 cm to 10 × 10 × 20 cm. Working with the Brown Stair indirectly prepares children for concepts in plane geometry, area, and volume through comparison, sequencing, observation, and understanding relationships between dimensions. It also gives teachers a practical tool for early math and geometry corners, supporting focus, logical thinking, and visual-spatial awareness in an organized educational environment.
