Abstract

Number sense refers to having a good understanding of numbers and operations and being able to apply the information to mathematical situations flexibly. Studies showed that there are some difficulties in determining students’ number sense just because it is not so easy to define the concept of number sense precisely. Therefore, researchers used different classifications of the componets of number sense in order to determine the students’ level of number sense. This caused having many different classifications of the components of number sense in the literature. The aim of this study is to examine the different components of number sense in the literature and to exhibit a framework to better understand the concept. First, different classifications of the components of number sense are studied by a through literature scanning. These different classifications are compared with the most comprehensive one in the literature to identify the components and their refering skills and also to discover the similarities and differences among the classifications. As a result of this study, it is established that a component covering the same skills is called by different names and also two different components are placed as one in another classification. Moreover, it is discovered that a component that is used to identify the existence of number sense has been used to identify another component in a different classification.
