Reach for this book when your child expresses frustration with multiplication or division, or if they feel like math is just a series of boring rules with no real-world application. Through a high-stakes science fiction lens, this graphic novel transforms abstract mathematical concepts into the very tools needed to save a family. It is a perfect choice for parents wanting to build confidence in STEM subjects while providing a story rooted in sibling cooperation and father-daughter bonding. The story follows Pera as she navigates a world where math is a superpower. When her father, a brilliant inventor, is trapped by a malfunctioning shrink ray, Pera must master multiplication and division to navigate the shrinking and growing mechanics of her environment. It manages to be educational without feeling like a textbook, emphasizing that mistakes are part of the process and that persistence pays off. This is a fast-paced, humorous adventure ideal for elementary students who thrive on visual storytelling and gadget-heavy plots.

An 8 to 10-year-old who loves graphic novels like 'Secret Coders' but struggles to see the point of long division. It is for the kid who likes taking things apart to see how they work.
This book can be read cold. Parents might want to keep a scratchpad nearby, as kids often want to solve the visual math puzzles along with Pera. A parent might notice their child shutting down during math homework or saying, 'I'm just not a math person.'
Younger readers will focus on the slapstick humor and the 'cool factor' of the shrinking tech. Older readers (9-12) will appreciate the clever way the math is integrated into the plot and will likely feel a boost in their own conceptual understanding.
Unlike many 'educational' books that pause the story for a lesson, this narrative makes the math the literal engine of the plot. You cannot understand the action without understanding the math, making it a true integration of fiction and STEM.
Pera's father is a scientist who has invented the Divmulti Ray, a device that can shrink or grow objects using division and multiplication. When an accident occurs, Pera's father is miniaturized, and Pera must venture into a world of skewed proportions to rescue him. To operate the machinery and solve environmental puzzles, she must apply mathematical logic in real time, effectively turning her math homework into a survival guide.
