Rowland's Knowledge Quartet (KQ) model can provide illuminating insights into teacher practice in mathematics classrooms. This paper explores a framework developed for pedagogical technology knowledge (TPACK) to consider teacher practice in integrated technology classrooms alongside the KQ model. Observations of a Year 11 class in an Australian school provides evidence that technology may impact practice in each of the four component areas, Foundation, Connections, Transformation and Contingency knowledge of the Knowledge Quartet model.
