The present invention relates to a teaching resource for studying mathematics, and more specifically relates to a teaching resource for studying mathematics having the effect of learning by repetition, wherein the teaching resource comprises: a cardinal-number sheet constituted by repeatedly laying out a plurality of unit numbers on a layer of cardboard; and number-display inducing sheets each of which has at least one transparent window and is placed over the cardinal-number sheet so as to induce predetermined study; being constituted in such a way that a plurality of the unit numbers laid out on the cardinal-number sheet are exposed in a limited fashion through the transparent windows of the number-display inducing sheets, such that children engaged in such study calculate problems by themselves following the basic rules of calculation, and, more particularly, such that said children can continuously and repeatedly study numerical problems of the same type while moving the transparent windows of the number-display inducing sheets.
