ABSTRACT:
A game and teaching device construction is described to include a plurality of indicia bearing blocks bound together by a pair of flexible straps. Each block is generally shaped in the form of a solid rectangle whereby a first strap is affixed to each block at one end thereof and a second strap is affixed to each block at the other end thereof. Each block includes front and back faces with one of such faces bearing indicia, for example a plurality of dots, and the other face bearing indicia of the number corresponding to the number of dots on the first described face. When stretched out, the construction is such that pushing the first block will cause the collapse of it and all other blocks in sequence. Furthermore, the construction can be used such that a child is interrogated to associate a number with the number of dots showing on a particular block, with the other face of the block being used to verify the child's answer.
