This work had the intention to conciliate the teaching of mathematics with very common practices in student s daily routine nowadays: the use of technology and communication through photography. With this objective, mathematical topics historically related to beauty and harmony were selected: the golden ratio and the Fibonacci sequence. Such approaches allow direct associations in other fields of knowledge like art, nature, the study of the human body which brought significance, culture, interdisciplinarity and criticism to the present study. On the other hand, photography also brings in its essence concepts of beauty, harmony and framing, making the development of creativity and innovation possible and allowing a break of the traditional methods in classroom. At last, the presented proposal defends the use of technology favoring the development of pedagogic proposals that boost the process of teaching and learning through the incentive of the guided use of cellphones in school. The proposal was experimented with 9th (ninth) grade students from a Rio de Janeiro municipal school and, it can be noticed that, the employed dynamics motivated the students, enabled academical and social growth and allowed the construction of creative and cooperative classes. Basic, mathematical and historical concepts of the chosen themes, as the proposal description and the results achieved in the experiments are exposed in the course of this work, which intends to be one more proposal to collaborate to the growth of basic education in the country.
