This thesis aims to provide new perspectives on Pascal s Triangle in elementary school. This is a rich subject and little explored in this school segment. It enables the development of interesting applications and curiosities that instigate the interest of the students and can promote a process of teaching and learning more effective. Through various approaches-gens can motivate or improve classical mathematics content of basic education as well as working with interdisciplinary situations. The paper presents a historical account of the emergence Triangle and its use over time by several mathematicians to Pascal. They are then presented and demonstrated mathematical results obtained from the analysis of the elements of this triangle. Finally, a collection of interesting approaches that relate the Triangle to various fields of mathematics are presented aiming to enable the primary education teachers use these proposals to create activities of your classroom. Some issues with mathematical concepts a little more advanced are also explicit allowing each teacher choice and adapt to their reality to those it considers relevant. The aim is to enable the teacher of primary school plus a support for building innovative educational proposals and contribute to the development of basic education more interesting and significant.
