    Fraction division is one of the least understood operations in school mathematics (Van de Walle, Karp, and Bay-Williams 2010). However, just having knowledge of the invert-and-multiply algorithm does not guarantee that students will recognize a problem situation involving fraction division. The National Research Council (2001) recommends teaching fraction division within a real-world context to enable students to build connections between whole number operations and division by fractions.
