FIELD: construction kits developing.
SUBSTANCE: present invention relates to developing construction kits, which include the main elements of a cubic shape, having protrusions on some faces and corresponding grooves on other faces, made with the possibility of fixing the main elements to each other by placing the protrusions of one main element in the grooves of another main element, and can be used for teaching, developing hand motor skills, logical thinking, design skills. According to the invention, the main element is a hollow frame in the form of interconnected cube edges, each edge is connected by a crossbar with only one edge opposite it on one face, each crossbar has paired protrusions arranged symmetrically, the paired protrusions have dimensions selected from the possibility fixing the main elements to each other by placing paired protrusions of one main element on the sliding grooves in paired protrusions of another main element.
EFFECT: expansion of the arsenal of developing construction kits.
