Claim Text:
1. A building element of a toy construction system, the building element comprising: a first wall positioned in a first plane, the first wall comprising an inner surface and an outer surface; a second wall extending orthogonally from the first wall; a plurality of male coupling elements of a coupling size extending from the outer surface of the first wall, the male coupling elements arranged in a 1 building unit (BU) grid on the outer surface, the 1 BU grid comprising a plurality of 1 BU intersection points that coincide with the male coupling elements; and a plurality of female coupling elements arranged relative to the inner surface of the first wall in a fractional BU grid that comprises a plurality of fractional intersection points, the female coupling elements comprising open spaces of the coupling size, the fractional intersection points comprising points that coincide with the 1 BU intersection points and points that are offset from the 1 BU intersection points, each of the fractional intersection points coinciding with one of the plurality of female coupling elements, the fractional BU grid positioning a number of the plurality of female coupling elements to receive male coupling elements of another building element in alignment with the 1 BU grid of the plurality of male coupling elements and positioning a number of the plurality of female coupling elements to receive male coupling elements of another building element in a fractional alignment offset from the 1 BU grid of the plurality of male coupling elements in a single dimension of the first plane.
