We did a task in the class to "improve" the beauty of the classroom, in other words, to decorate it.
All the classroom opened a Pinterest account, to upload photos, and the most liked photos will be printed and the teacher will paste them in the classroom. Here's one link to my pinterest profile, and another to the classroom's posters.
