The Quiz-It Set is an interactive educational book and smart pen collection from PI Kids (Phoenix International Publications), designed for young children. This Costco bundle includes 12 spiral-bound activity books paired with an electronic Quiz-It Pen that delivers instant audio and visual feedback.

Children use the smart pen to touch answer stars printed on each book page, testing their knowledge across hundreds of multiple-choice questions. The pen lights up and plays sounds to congratulate correct answers or encourage another attempt for wrong ones. Topics covered include letters, numbers, counting, colors, shapes, Spanish vocabulary, Language Arts, Math, Science, Social Sciences, and Fine Arts.

Each spiral-bound book is designed for durability and repeated use. The smart pen runs on replaceable AAA batteries and is compatible across the full Quiz-It book series, making it easy to expand the collection over time. The set is ideal for preschool and early elementary-aged children learning through hands-on interaction, and well-suited for quiet time, car trips, or at-home learning.
