The objective of this work was to perform an approach about quadratic functions raising about their applications in the daily life of students of the 1st Year of High School. For this, we counted on the collaboration of the 1st grade class of the IFPI Agricultural Technician. The same was divided in four moments: presentation of the main concepts on the subject, demonstration of the construction of the parable, accomplishment of practical activities and, resolution of problems involving quadratic functions. Aiming at a better dynamicity in each stage, he proposed to divide the class into six groups, which were called G1, G2, G3, G4, G5 and G6. It should be emphasized that in all activities the groups corresponded satisfactorily in the development of each activity. As for the last activity, the group that obtained the highest score was G6, and G1, G2 and G4 obtained the worst score.
