Fun-to-Know® Puzzles are bright, engaging, and durable learning tools that make a game out of building basic skills. Colorful photos of high-interest real-world objects draw attention and clear, bold text is easy to read. Students can learn at their own pace with self-checking pieces - only the correct tiles fit together. Puzzle tiles have matching activities on both sides! Great for home and travel, in daycares and classrooms, and in therapy and care facilities, too. In this set, twenty-six 2-piece puzzles help build learners' alphabet recognition and vocabulary. 52 pieces in total measure 3" x 3" and come in a sturdy storage box. Made in the USA for reliable quality and product safety. Recommended for ages 3 and up.
