## How do you teach a Venn diagram?

When teaching Venn diagrams, start with the basics: Explain that Venn diagrams use overlapping shapes (usually circles) to show relationships. Each circle contains a set. Where the circles overlap, the two sets have something in common.

The set made by combining the elements of two sets. So the union of sets A and B is the set of elements in A, or B, or both. The symbol is a special “U” like this: ∪

## How do you explain a Venn diagram?

A Venn diagram is an illustration that uses circles to show the relationships among things or finite groups of things. Circles that overlap have a commonality while circles that do not overlap do not share those traits. Venn diagrams help to visually represent the similarities and differences between two concepts.

## How do you explain Venn diagram to students?

## What does AUB mean in Venn diagrams?

Union of SetsThe union of A and B is the set of all those elements which belong either to A or to B or both A and B. … Now we will use the notation A U B (which is read as ‘A union B’) to denote the union of set A and set B. Thus, A U B = {x : x ∈ A or x ∈ B}.
