Students of the 303 Z class are flying in a spaceship on an excursion to Mars. The motto of their teacher: "Space exploration must begin with yourself!" This motivating story helps kids set clear goals, teaches them how to stay focused in class and avoid mistakes on tests, and how to avoid spending too much time on social media and TV.
