Abstract
This paper reports on part of a larger study to compare students? computation and estimation skills. Year 7 students in the Perth Metropolitan area were given a computation test and an estimation test of matched items. The performance on computation was 10 percentage points higher than on estimation. It was clear that students? computations tended to be undertaken mechanically rather than meaningfully. In particular, students were weak at fractions and decimals and showed significant misconceptions. It is recommended that much more time be devoted to estimation as an essential and integrated process in the mathematics classroom.
