Abstract
Forty-five Grade 7 students from a larger sample of 118 were interviewed on the thinking
strategies they used in solving number sense problems. Students were categorised into
high, middle and low ability groups. Students were asked a series of questions designed to
assess the thinking strategies they used in solving number sense questions. The study also
investigated the extent to which misconceptions and learned rules were sufficiently fixed
that they continue to influence students’ responses despite having been given lessons on
number sense. Results show that many students continued to apply rule-based methods in
attempting to solve number sense questions.
