Overview
The child arranges ten brown prisms in sequence from thickest to thinnest, creating a stair-like formation. Unlike the Pink Tower which varies in three dimensions, the Brown Stair isolates variation in two dimensions (width and height) while length remains constant at 20cm.
Objectives
What the child gains from this work
Discriminate between ten gradations of thickness (width/height). Develop visual judgment while length remains constant. Strengthen gross motor skills (the thickest prisms are heavy). Build concentration and patience through careful sequencing. Prepare indirectly for mathematical concepts (square numbers).
