1. A method of teaching characteristics of latticework structure comprising the steps of:

  • demonstrating the commonality of lattice structure of (a) latticework arranged in accordance with a tetrahedron configuration and (b) latticework arranged in accordance with a pyramid configuration which has (i) a four-edge base and (ii) four faces that extend from the base and meet at a point, said demonstrating step including the steps of;

    positioning a plurality of structural members relative to each other to define spacepoints in a latticework arranged in accordance with the tetrahedron configuration; and

    positioning a plurality of structural members relative to each other to define spacepoints in a latticework arranged in accordance with the pyramid configuration;

    wherein said positioning steps include;

    merging together structural members along at least one face of the latticework arranged in accordance with the tetrahedron configuration with structural members along at least one corresponding face of the latticework arranged in accordance with the pyramid configuration to make the spacepoints along at least one tetrahedron face coexistent with the spacepoints on the at least one corresponding pyramid face.
