Synopsis

Crack the case with George Cornelius Factor in this entertaining math adventure that introduces simplified and reduced fractions with equal parts intrigue and humor.

When a valuable fraction goes missing, George Cornelius Factor (a.k.a. GCF) vows to track it down. Knowing that the villainous Dr. Brok likes to disguise his ill-gotten fractions, GCF invents a Reducer—half ray gun, half calculator— that strips away the disguise, reducing the fraction to its lowest common denominator and revealing its true form. With the Reducer in hand, George seeks out Dr. Brok in hopes of retrieving the missing fraction.

Back matter includes more detail on simplifying, or reducing, fractions.

Some kids collect baseball cards. Some collect action figures. Me? I collect fractions. I've been collecting them for exactly ? of my life. In my bedroom, shelves full of fractions cover ¾ of my walls. Maybe it's because I was born during a half moon. Or maybe it's because I'm ¼ genius, ¼ stubborn, ? determined, and ? crazy. But for me, it all adds up to one thing: I can't get enough of those darn fractions.
