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

Select elements correctly through nested operations involving three sets.

Worked example

A = {1, 2, 4}, B = {2, 3, 4}, C = {4, 5}. Find (A ∩ B) ∖ C.

{2}

The intersection A ∩ B is {2, 4}. Removing elements in C removes 4 and leaves 2.

Teaching notes

Make the practice count

  • Find the inner result before applying the outer operation.
  • Include center elements in every relevant pair intersection.
  • Use the displayed universe for complements.
  • Check answers by testing individual elements against the expression.
