2010). Teachers in the OGAP studies also recognized that instruction might have unintentionally reinforced inappropriate whole number reasoning. 6). This observation made by teachers points out the importance of students having experience, even in the early grades, of physically partitioning sets of objects or areas in which the number of objects or parts in the whole is a multiple of the denominator. 7, students need to use fractional reasoning to reflect on the meaning of the numerator and denominator and the relationship between them in order to partition the set correctly.

For example, teachers in the OGAP Exploratory Study (OGAP, 2005) reported: • Using a greater variety of visual models in their instruction • Making explicit links between visual models • Providing more opportunities for students to use visual models to solve problems • An increase in the use of number lines.
