This work presents a proposal to introduce the study of vectors in High School, in order to oer a broader and clearer possibility for some mathematical demonstrations, applications and their use in other elds, such as Physics, for example. Make some demonstrations of trigonometry, of analytical and at geometries more playful and understandable, is the objective of this approach, besides, of course, oer conditions to work with vectors already in High School, oering pre requisites for future studies in the areas of Exact Sciences.
