Improved school blackboard, characterized essentially because its board is constituted by the combination of two panels, a metallic receiver of figures or magnetic letters, while the other panel is made of wood and constitutes the surface on, which can be written, being both joined panels by means of a perimeter fence, so that, indiscriminately, one can use any of the faces that it determines, each panel through the turn given to the board.
