The purpose of this study is to examine the effects of an explicit Concrete-Representational-Abstract (CRA) approach that emphasised conceptual knowledge of fractions on low-achieving sixth-grade students. Participants were 34 sixth-grade students, of which 10 showed low achievement in fractions (LA...
