Abstract: Computer models for self-assessment on the topic of central symmetry are presented. Given a prototype and an image in central symmetry, it is required to indicate its center. The use of these tasks-games promotes the development of the estimation by sight, as well as the formation of skills for applying the properties of central symmetry. The freely available electronic resources are developed with dynamic GeoGebra software and are provided in the Virtual Mathematics Laboratory, developed at the Institute of Mathematics and Informatics of the Bulgarian Academy of Sciences.
Keywords: symmetry, digital competences, GeoGebra, estimation by sight, self-assessment, gamification, educational tools.
