Justin Krasner

Justin Krasner is a children’s author and “bookmaker” known for blending education, creativity, and play into his work. Describing himself as a lover of learning, mischief maker, loud laugher, and curious kid who can’t grow up, Krasner creates books that engage children not only through words but also through interactive experiences. Based in Brooklyn, New York, he brings an inventive spirit to every project, aiming to make learning an adventure rather than a chore.

One of his most notable contributions is the TinkerActive Workbook series, which includes titles like TinkerActive Workbooks: 1st Grade Math and the TinkerActive 1st Grade 3-in-1 Workbook, covering Math, Science, and English Language Arts. These books combine traditional workbook exercises with hands-on tinkering activities—such as building projects, experiments, and problem-solving challenges—that encourage children to actively explore concepts. This integration of STEM and creativity helps young learners develop critical thinking skills while having fun.

Krasner has also authored Crinkle, Crinkle, Little Star, a sensory board book that reimagines the classic lullaby with tactile crinkle elements and starry illustrations. Designed for the youngest readers, it stimulates multiple senses while fostering early language and literacy skills.

His work is defined by a commitment to interactive learning, where books serve as tools for discovery rather than passive entertainment. By infusing humor, curiosity, and a touch of mischief into his content, Krasner engages children’s natural desire to explore the world around them. He approaches bookmaking as an act of crafting experiences, carefully considering how each element—from design to activity—can inspire participation and wonder.

Through his inventive projects, Justin Krasner has established himself as a distinctive voice in children’s publishing. His books invite young readers to play, experiment, and imagine, ensuring that education is not just informative, but joyfully hands-on and memorable.
