USO DO SOFTWARE GEOGEBRA COMO FERRAMENTA PARA APLICABILIDADE DA NÚMERO DE OURO NA EEMTI PROFESSOR CLODOALDO PINTO

The motivation of this work is revealed in concern to discuss issues related to daily life and explain them in an attractive manner so that the student can absorb the information necessary for learning content more appealing as possible, thereby facilitating their learning. The objective of this work is to show the importance of the Golden Ratio to the study of geometry and number sequences in high schools, to understand how mathematicians have made to reach the golden ratio using algebraic and geometric concepts and situations that used to show whether or not the number gold, as the issue involving the Egyptian pyramids, the use of the golden ratio by Leonardo da Vinci, the relationship of this number to the Fibonacci sequence, the application in botany and so on. The methodology was used to conduct literature surveys on books and works done in this area and applying an activity involving the use of GeoGebra software and other related sequences with high school students addressing the content. Results were a little difficult in the initial handling with the software, but a high level of concentration and excitement after the transmission of the history of building the number of gold and as can be observed in nature.
