Abstract
This study examines the views held by students from an inquiry classroom. Individual interviews were used to explore views held by a group of 9-11 year old students towards explanation and justification of their mathematical reasoning. Responses indicated that the students viewed explanations as thinking tools. Challenge, questioning and debate were viewed as opportunities to re-construct mathematical thinking. The study emphasises the need for a safe, power sharing environment to support student construction of positive mathematical attitudes and dispositions.
