5. What is a Venn Diagram
•A diagram that consists of circles.
•The circles represent the elements of the
set and the outer parts represent elements
that are not part of the set.
•A Venn Diagram is used to organize a list
of data.

6. History of Venn Diagram
Venn diagrams were introduced around 1880 by John
Venn. They are used to teach elementary set theory.
(*Set theory is the branch of mathematics that studies
sets, which are collections of objects)
It is also used to illustrate simple set relationships in
probability, logic, statistics, linguistics and computer
science

7. Can the Venn Diagram be used in
other classes?
As graphic organizers, they allow students to formulate their thoughts.
With the two above, students might list the similarities between the
republicans and democrats in C and the differences in A or B. History
students might use Figure 1 to compare Athens and Sparta in ancient
Greece. Or they might compare the North and South in the period leading
to the American Civil War.

9. Creating a Venn Diagram together…
•Write down your 6 most favorite numbers.
•Put them in order from biggest to smallest.
•On your Venn Diagram, label the 1
st
circle as
numbers that have 1 included in the number
and the 2
nd
circle as number that have 9
included. The middle circle will be numbers
with BOTH 1 and 9. The outer parts of the
Venn Diagram will be numbers with neither 9
or 1 included.
