This lesson is a collaborative thinking task rooted in co-creation, where students work in small, randomly formed groups at VNPS. Each student uses a different coloured marker so contributions remain visible. Each student begins with quick, individual marks to introduce ambiguity and reduce pressure. A curricular theme is then introduced as a guiding question, shifting the task toward purposeful thinking. Through a series of 20-second timed rounds, students build on one another's ideas to transform the marks into a shared visual. In the final phase, they extend their thinking by contributing to a shared written narrative. The focus is on collective thinking, iteration, and meaning-making, where students build knowledge together rather than working in isolation.
