Abstract

Device for checking the results of mathematical and similar operations, essentially characterized by the fact that it comprises two components, one of which appears printed in the exercise book together with the boxes where the numbers and/or signs of the result to be scored must be written, while the other component is in the exclusive power of the teacher or qualifying person, whose second component is constituted by a transparent film that when superimposed on the printed component produces in combination with this, a design corresponding to a pre-established key.
