They are preparing some fun activities to make the classes more fun and not as boring as teachers usually do. They make fun games on the whiteboard, where the students of 4th ESO can play the games they prepare. The games they do are usually: Crosswords, Kahoot....
These class preparations are useful for them to learn a lot more, because they do more preparing than just being students and then on the exam they can use all their knowledge they got during all the unit.
