The project will be based on cartoon 3D environments representing selected cultural routes, one in each country. In these environments, with the help of different math puzzles the students will be able to interact with the 3D objects solving these puzzles and getting points, rewards and badges. The innovation of the 3D games is that those will be available on web browsers (WebGL) and tablets, and that the puzzles will be dynamically updated by the teachers through their web browser or tablet. Teachers will be able to select the mini-games they want, customize and translate the content, add narration, select the rewards and set up a personalized training path for each trainee.
