In this episode, the subtraction of fractions is related to the subtraction of whole numbers. The borrowing process is introduced with a story that gives a concrete picture of what one is doing when borrowing in a fractional subtraction exercise, and followed by a logical, step-by-step process developed to subtract mixed numbers. Special cases involving a mixed number minus a whole number and a whole number minus a mixed number are also investigated. Grades 3-7. 30 minutes on DVD
