Finally! Schools are closed, summer is here, and vacations have begun. Happy holidays mean rest, swimming, walks in nature, friends… But it also means quiet afternoons with a book that has it all: puzzles, stories, games, crosswords, math! In other words, an opportunity to review what we learned in winter in the most enjoyable way! 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, but also to expand their knowledge.
