In this tasks, students are given pairs of open statements and asked to determine the relationship between their truth sets via generating their own Euler diagrams. This can be used as a first task after students have been given the definition of the truth set of an open statement and been introduced to visualizing truth sets via Euler diagrams.
This task is based on the following research article:
Hub, A., & Dawkins, P. C. (2018). On the construction of set-based meanings for the truth of mathematical conditionals. The Journal of Mathematical Behavior, 50, 90-102.
