Fractions in Disguise
When the valuable fraction, 5/9, 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-begotten fractions, GCF creates a Reducer - a tool for simplifying fractions and revealing their true forms. Following Dr. Brok to his mansion, GCF uses his Reducer to root out the treasured 5/9, which has been cleverly hidden in plain sight. Equal parts action and humor add up to an entertaining introduction that should help take the fear out of fractions. Ages 7 to 10.
