A dinosaur, Ross, decides to spend a pleasant summer. He escapes from the pages of the History book, becomes friends with Dimitris, who has just finished the third grade, and travels with him. They say that dinosaurs had little ...brains. However, Ross is a math whiz. He solves crosswords and puzzles, humorously comments on what happens around him, and proves to children that even the most difficult exercises become fun when solved with enthusiasm and a good heart.
Have a great summer with Ross and onwards!
