Throughout the inquiry, learning was strongly driven by students’ questions. Questions such as “What do we need to prepare?”, “How should we set the price?”, and “How can we attract more customers?” led naturally from one to another, deepening the inquiry. The children applied their learning from these questions to the planning and running of the flea market. Through this question-driven, transdisciplinary process, they demonstrated strong agency, reflection, collaboration, and the attributes of young IB learners.
