Abstract
Gap thinking has been categorised as one of several whole number strategies that interfere
with early fraction understanding. This study showed that this claim is not supported by
interview data of Grade 6 students’ gap thinking explanations during a fraction pair
comparison task. A correlation with equivalence performance was uncovered, leading to the
suggestion that the additive nature of gap thinking may actually reveal the (erroneous)
additive nature of students’ early engagement with equivalence concepts.
