The aim of htis project is to stimulate interest in maths by displaying different parts of mathematics (geometry, cryptography, topology, statistics, logic, etc) with hands-on games and materials. Participants have to face the challenges guided by students and maths teachers. Students will also search for typical games of their countries (such as parchis or backgammon) and will explain the rules to the rest of participants. In addition, students will work on different aproaches to chess (history, rules, culture, competitions, etc.) and will participate in an international online competition.
