Pedagogical templates, characterized by the fact that they are constituted by at least two rigid sheets, adaptable peripherally, by one of whose faces are provided with patterns plotted against the background, these patterns being constituted in segments of the totality of some lines or figures capable of being completed by the juxtaposition, combined at the discretion of the user, of a plurality of said sheets by any one of the edges thereof, so that the ends of said segments coincide, and with the particularity that said ends are equidistant in all the sheets, whatever the configuration in them of the segments, of determined and common points of their periphery, such as the vertices if they are polygonal pieces or the polar areas if their configuration is arched, which allows to vary the drawing of the figures constituted by the conjunction of the segments of the plates, without altering in any in case the regularity of the assembly of the same.
