Summer B elementary school (new edition)

What happens, really, when a hare and a turtle meet in the pages of a book that aims to keep cool for the summer the knowledge that the children acquired at school, but also to teach them new things in a fun way?
Simply! They also become commentators, solve exercises, crossword puzzles, quizzes and participate by commenting on everything with fun and humor, each from his own side.
The hare is in a hurry, the turtle is slow, they wish you a good summer through the “Summer”!
