Part learning companion, part magic wand, these interactive pens talk, laugh, light up and even buzz with excitement as children explore. Designed for little hands, these electronic pens cheer for correct answers and gently redirect children when they answer incorrectly, allowing independent discovery. They engage your youngest learners with easy-to-use technology. Simply press the pen down on the cards to answer and receive feedback. Using the pen offers students the opportunity to prepare for school or catch up where they need support. Each pen requires two AAA batteries (sold separately) and is recommended for students ages 3 and up. All five are compatible with all Hot Dots and Hot Dots Jr. sets.
