This work deals with the teaching of some concepts on recurrent equations taking in account the cobweb.The method used to construct the cobweb is easily assimilated, and has connection with topics of high school and helps students to think recursively with the support of a geometric point of view, in a predominantly algebraic environment .It will be presented strategies for solving linear recurrences of the first and second order, seeking to leave high school teachers to be understanding the concepts, allowing in this way applications in their classes. Furthermore, the work deals with singular points and stability in the non-linear case. Finally ideas are given for practical training of students in class.
