This study examined computational estimation strategies of the seventh grade students. A case study methodology was used and data were collected from five high achievers via an interview session. During the interview participants were required to solve fifteen computational estimation numerical questions which were presented in whole number, fraction and decimal and they were asked to explain their reasoning. A theme oriented matrix was used to analyze the data. The results of the study found
