Edge Models with the CAD Software: Creating a New Context for Mathematics in Elementary School

Abstract Digital media have become increasingly important in recent years and can offer new possibilities for mathematics education elementary schools. From our point of view, geometry geometric objects seem to be suitable the use computer-aided design software classes.
