Reach for this book when your child starts viewing math as a chore or feels overwhelmed by the abstract nature of fractions. It is the perfect tool for a child who loves a good mystery but perhaps lacks confidence in their arithmetic skills. By framing mathematical simplification as a high stakes detective mission, the story removes the fear of 'getting it wrong' and replaces it with the thrill of the hunt. The story follows Mr. Factor, a clever investigator who uses a specialized tool called the Reducer to unmask fractions hiding in disguise at an auction. Beyond the math lesson, the book explores themes of perseverance and the satisfaction of solving a complex puzzle. It is ideal for elementary schoolers who enjoy humor and logic, offering a playful way to reinforce classroom concepts through a narrative that feels like a classic noir caper.
None. This is a secular, logic-based adventure with no heavy emotional or social baggage. It is entirely focused on the concept of mathematical simplification.

Sign in to write a reviewAn 8-year-old who is currently struggling with the leap from whole numbers to fractions. This child likely prefers stories with gadgets, 'top secret' missions, and quirky adults. It is especially effective for the 'reluctant mathematician' who needs a narrative hook to engage with numerical concepts.
This book can be read cold, but parents might want to have a piece of paper handy to mimic the 'reducing' process alongside Mr. Factor to make the concept tactile. A parent might see their child staring blankly at a page of equivalent fractions or expressing frustration that '5/10 and 1/2 are not the same thing.'
Younger children (7) will enjoy the colorful, wacky illustrations and the 'search and find' aspect. Older children (9-10) will appreciate the pun-heavy humor and the actual mechanics of the division shown in the art.
Unlike standard textbooks or dry workbooks, this book personifies numbers. By making the fraction the 'disguise,' it transforms a rote procedure into a logical necessity for the protagonist's success.
Mr. Factor is a fraction collector on the hunt for a very specific prize: the 5/15. However, at the auction, all the fractions are 'in disguise,' appearing as larger, unsimplified versions of themselves. Using his trusty invention, the Reducer, Mr. Factor must divide the numerators and denominators by their greatest common factors to reveal their true identities and reclaim his treasure.
