As in project is written that students need to have some additional classes in English, Croatian Erasmus group of students started to do it with English teacher Ingrid. They learn some special words important for this project, or for math at all. They are playing some math games and talking in English about it. In this way students are learning to be creative, interactive and sociable in Croatian and English. It would be huge help to start conversation and team working on international meetings.
Also Math teacher Goran Kupčerić showed pupils official web-site of project https://playingwithmaths.eu/ .
