Understanding Union and Intersect

Each worksheet has 12 problems identifying the shaded portion of a Venn Diagram.

Student Objectives

Practice reading three-circle Venn diagrams and identifying which regions are shaded
Write set notation using union (∪), intersection (∩), and difference (−) to describe shaded areas
Combine multiple set operations in one expression, like B∪(A−C)
Understand the difference between union (everything in both), intersection (only the overlap), and difference (in one but not the other)
