Learning card system for children, has learning cards with shapings corresponding to edge shapings, where shapings counteract relative movement of learning cards along edges that lie together during mutual contact of edges

摘要

The system has a set of learning cards (100) that are individually surface-shaped, where two edges of each learning card have non-even edge shapings. The learning cards are positioned together without gap and have shapings corresponding to the edge shapings. A control pattern reproduces a representation of gap-free arrangement of the learning cards. The shapings counteract relative movement of the learning cards along the edges that lie together during mutual contact of the edges.
