The diagram is the source of every answer
Each element appears in one region. Use its membership to evaluate the expression and write a roster set without repeats. The two-set activity has three diagram groups; the three-set activity uses one diagram for ten questions.
Choose a focused set of options while learning the notation. The preview and downloadable PDF contain the same questions, with the answer key kept separate from the student pages.
Learning objective
What this activity builds
Evaluate an expression by selecting the actual elements in its diagram regions.
Worked example
If A = {2, 4, 6} and B = {4, 5}, what is A ∪ B?
{2, 4, 5, 6}
A union includes elements in either set. The shared element 4 appears only once in the answer.
Teaching notes
Make the practice count
