The concepts that are central to the curriculum are presented in the form of key questions. It is these questions, used flexibly by teachers and students when planning an inquiry-based unit, that shape that unit, giving it direction and purpose. It is in this sense that the key questions, and the concepts to which they relate, are said to drive the PYP curriculum.
PYP key concepts and related questions:
Form: What is it like?
Function: How does it work?
Causation: Why is like it is?
Change: How is it changing?
Connection: How is it connected to other things?
Perspective: What are the points of view?
Responsibility: What is our responsibility?
Reflection: How do we know?
