The present work presents a proposal of using the GrafEq software for teaching equations and inequalities. We usually find works for elementary school more easily than for high school, mainly when it comes to methodology or the use of technology itself. For this reason, this study discusses the need for the teacher to look at the specificities of teaching for the adolescent students and also at their interests and motivations. Technology, if used correctly, can be very useful in the teaching of mathematics, since it is a discipline that attracts the interest of few people. Thus, the application of technology in the teaching-learning process can be an important tool for a more effective teaching practice. Considering the large number of adolescent students who present difficulties in learning mathematics using the traditional methodology, the aims of this study were to theoretically discuss the elements that may favor the mathematics teaching; and also offer educational products, as an tool, so that the teacher can make the math classes more attractive and productive through contact with GrafEq software and suggestions for activities with illustrative examples, thus bringing art and technology into the classroom. Based on Vigotski (2010), Marques e Oliveira (2016), Roehrs, Maftum e Zagonel (2010), Zanella (1994), Oliveira (2009), Almeida (2006), Otto (2016), Souza e Rousso (2011), a qualitative exploratory research, through a subjective investigation of the literature, we developed a proposal seeking to value the social and cultural environment of these adolescents, and suggest to the teacher a mathematical teaching in which there is interaction between the young students and the activities promoted. For product development, using the GrafEq mathematical software as a resource, an e-book and video-classes on the YouTube channel with mathematical explanations were structured. After the bibliographic survey, we noticed a certain restriction regarding the amount of materials that it addressed about the GrafEq software, which made the search a little more difficult. The developed materials were made available to teachers in the area.
