Participants will fold creases to a single point on a sheet of paper. They then make conjectures about the necessary and sufficient conditions for the sheet to fold flat at that point. By cutting the folded paper they can generate arguments to support their conjectures and observe angle and circle theorems in an unfamiliar context.
