Abstract
A shape-matching educational toy apparatus includes a first plate having a plurality of different shape apertures therein and a plurality of block elements of corresponding shapes which are receivable in the apertures. The block elements are retained in the apertures by resilient retaining elements until a second plate engages the block elements to push them therethrough. The second plate is hingedly attached to the first plate but resiliently upwardly displaceable relative thereto whereby when an obstruction such as a child's finger is interposed between the plates, injury is avoided.
