Overview
The child explores three-dimensional geometric forms through touch and sight, learning to identify and name each solid. The set typically includes: sphere, cube, cylinder, cone, ovoid, ellipsoid, triangular prism, square-based pyramid, and rectangular prism.
Objectives
What the child gains from this work
Identify geometric solids by touch (stereognostic sense) and sight. Learn precise geometric vocabulary through the three-period lesson. Discriminate between curved and flat surfaces, edges and vertices. Develop spatial reasoning and geometric awareness. Prepare for later geometry studies.
