The project started in September 2018 as GeoUniud a user-friendly platform at the University of Udine, where lessons and exercises are stored and organized with a careful use of randomized controlled contents as exercises, geometrical pictures and abstract reasoning. The lessons are augmented by a virtually infinite collection of examples, and by interactive representations of concepts. The training pages offer randomly generated exercises, along with a system in place to verify the student's answers, flagging errors and giving contextual feedback. The platform stores information about the user's performances. Starting to support first year Linear Algebra students of Math degree, it is currently moving into MatUniud, covering all the basic mathematics courses in the STEM Area of University of Udine. In this article we will show, as example, tools for system of linear equations inside a linear algebra course for engineering students.
