Pupils from one country work in groups and start making cardboard containers for rubbish in 4 colours : blue, green, yellow and brown. The partner school finishes the containers sticking a paper on them with the proper category name: paper, glass, plastic, food. Each country creates pictures of rubbish using TIK, prints them, cuts them out and segregates them to the right container writing their names in English. In this way they finally create a book called “ The Youngests’ Guide Book about rubbish segregation” for their school colleagues and peers (two versions of the book: paper and online ones)
