Blood Types and Set Theory

Prepared by Shari Davis and Katherine Smith as part of a series of supplemental critical thinking explorations to promote discovery and deeper comprehension.
This project was supported by a 2017 Faculty Innovator Grant through Old Dominion University’s Center for Learning and Teaching.

Part 1

Getting Ready

Before beginning this exploration, students should have basic familiarity with set theory and Venn diagrams. Completing CReaTE 3 is a good place to start.

Video

Students should watch the following video: Critical Thinking Exploration 5 Part 1 Video

Follow-up

After watching the video, students should be given time to think about which blood types can accept blood that is A⁻ and B⁻. This could take place in class, after class or using an online discussion board.

A sample discussion board prompt would be: Take a few minutes to think about which blood types can accept blood that is :

  • A⁻
  • B⁻

Part 2

Getting Ready

Students should have viewed Part 1 of this exploration and had time to complete the follow-up activity.

Students should watch the following video: Critical Thinking Exploration 5 Part 2 Video

Follow-up

This concludes the series. Hopefully, you and your students have enjoyed it and they will continue to be engaged in critically thinking about mathematics.
