Scratch is a tool for initial learning of programming, but also for creating educational and entertainment content, making mathematical and scientific projects, simulating and visualizing experiments. This paper examines the effectiveness of Scratch's application in mathematics, in the study of basic geometric shapes. The analysis has shown that there is a statistically significant difference in achievement among students who have learned the basics of geometry based on the perception and recognition of geometric shapes on models and bodies and those who have used the programs implemented in Scratch. The results obtained are in a positive correlation with the students' overall school performance and show that there are no differences in achievement between boys and girls. Scratch is an environment that has allowed mathematics to become more interesting and interesting to students.
