Abstract

In the present work, all the information regards the process of implementation, execution and evaluation of sequences of mathematical tasks with algebraic generalization activities applied to ninth-year students of E.G.B. It shows the analysis of results of four activities with pictorial sequences, in which students explore, recognize and mention patterns, as well as analyze the change, the increase or decrease

of the form or value in a geometric sequence, by a set of regular polygons (pentagons), the design of the tiled floor of a room, a bucket of eggs, and in the last one it is considered the main source of economic income of families in the floriculture sector.
