Finally! Schools are closed, summer is here, and vacations have begun. Happy holidays mean relaxation, swimming, nature walks, friends... But they also mean quiet afternoons with a book that has it all: puzzles, stories, games, crosswords, math! In other words, an opportunity to review in the most pleasant way what we learned in winter! The books in the "Happy Holidays" series have been revamped and adapted to keep company with children who want to play while reviewing school material and expanding their knowledge.
