We plan to make mathematics fun by adapting some of the games used today to mathematics subjects. In addition to these games, the partners will also design their own local games based on mathematics topics. In this way, partners will share the games they have designed with each other and play these games with each other online. Students from different countries will be in contact both during the design phase and during the playing phase of the games. In this way, students' creative abilities, language development and socialization will be supported.
