This study investigates three teachers’ uses of a dynamic geometry program (The Geometer’s Sketchpad) in their high school geometry classes over a 2-year period. The researchers examine teachers’ actions and questions during pivotal teaching moments to characterize mathematics instruction that utilizes technology. Findings support an association between teacher–tool relationships, predominant teacher actions, and questioning.
