A dinosaur, Ross, decides to have a pleasant summer. He escapes from the pages of the History book, becomes friends with Dimitris, who has just finished the 3rd grade, and travels with him.

They say that dinosaurs had little... brains. But Ross is... a mathematical whiz. He solves crosswords and puzzles, comments humorously on what happens around him, and proves to the kids that even the most difficult exercises can be fun when solved with enthusiasm and an open heart.

Have a great summer with Ross, and let’s go!
