This study sought to determine the estimation processes used by 10 urban middle school students for solving computational estimation problems, and if there was a difference in the estimation processes utilized for straight computation and application problems. An adapted model of the Accessing Computational Estimation Test (ACE) was used to determine the estimation strategies employed by the subjects within timed and un-timed settings. Qualitative methods were used to analyze the data. The timed ACE tests were administered using an interview format and included computation and application problems. The findings indicated that there were no differences in estimation processes for straight computation and application problems; however, students performed better on timed tests for application problems.
