During years of teaching in high school, I have shared the difficulties encountered by students in understanding the topic "Functions". These difficulties affect the understanding of other topics within mathematics and in some related disciplines that depend on the good construction and understanding of functions. In this sense to propose innovative mechanisms for the teaching of mathematics, we use a mathematical software Dynamic Geometry, called GeoGebra to be a tooling to assist the functions of education through construction of workshops and modeling them. To be a recurring theme and great application in mathematical studies and related areas, it is interesting to use different mechanisms for progression of Education and its applications, in each year of high school. The study of functions is better absorbed and can measure in the display such mathematical object is realized in a systematic way. In addition to using the software with a graphical builder animation tool allows students to motion graphic display according to the variation of the coefficients. Search tools for a better understanding of this important topic , combine the playful aspect to teaching, trying to captivate the student so that it can be interested more deeply in the subject , aiding their learning. GeoGebra has the ability to "plotting" (in mathematical jargon: "draw") graphics in the form (general) literal and still has a tool that allows the graphics animate what we intend to exploit to facilitate students' understanding of the study of these functions. Through activities (workshops) using co - teaching technology allow students to enjoy a growing knowledge of the characteristics of the selected functions, namely: order, quadratic and exponential, with direct application in procurement issues / similes
