Today students are well familiar with technology as they are using it from birth day, they are surrounded by computers, mobile phones and other tools of digital age. The aim of the research was to determine whether there was any difference in the achievements of the students on subject of Square, rectangular and triangular sides in Geo Gebra program during new age class system and traditional classes on subject length as line connecting two dots. Experiment was done on group of 17 students, divided in two classes of elementary school Trstenik. Basis those researches and interception of results we sow that GeoGebra program has significant role in studying of new material. Results of research where better working on sophisticated way of working in program GeoGebra comparing with traditional way. We can say that this program perfectly fits for mathematics, specially geometry and students are more happy working with this program which can be seen by the result of satisfaction survey GeoGebra has become leading program which represents dynamic of mathematics, it supports science, technology, mathematics, education, and innovation in classes and studying in the whole world. Results of this research are proof for that, all is needed is wiliness and persistence of teachers so that they can transfer they knowledge to their students..
