Summer C’ Elementary (new edition)

A dinosaur, Ross, decides to spend a pleasant summer. He leaves the pages of the history book, becomes friends with Dimitris, who has just finished DG Elementary School, and travels with him.
They say that dinosaurs had a little. Mind. But Ross is… a mathematical head. He solves crossword puzzles and riddles, humorously comments on what is happening around him and proves to the children that even the most difficult exercises become fun, when they are solved with fun and a good heart.
Have a nice summer with Ross, and go ahead!
