Lesson Transcript
Instructor: Jeremy Cook

I have been teaching elementary school for 16 years. I have extensive experience in lesson and curriculum development and educational technology.

Have you ever had to compare and contrast two different things? If so, you could have used the help of the Venn diagram. In this lesson, we'll discuss the Venn diagram and look at examples of this useful tool.

What Is a Venn Diagram?

Say you're standing in front of two adorable puppies and you get to bring one home - but only one. How do you decide? In order to make the best decision, you could use a Venn diagram to map it out.

A Venn diagram is a visual brainstorming tool used to compare and contrast two (sometimes three) different things. Comparing is looking at traits that things have in common, while contrasting is looking at how they differ from each other.

A Venn diagram is made up of two large circles that intersect with each other to form a space in the middle. Each circle represents something that you want to compare and contrast. Where the two circles intersect, you would write traits that the two things have in common. In either side of the intersecting space, you would write the differences among the two things.

When there are a lot of traits in the middle space and not a lot in the outer circles, the things are very similar. And if there aren't many traits in the middle and a lot on each outer circle, the two things don't have much in common.

Creating a Venn Diagram

Now, let's create our own Venn diagram to choose which puppy you want to take home with you. One of the puppies is a poodle and the other is a Great Dane.

Start by writing down lists of information about each puppy, including important characteristics and details that will help you compare and contrast. For example, you know you want a puppy that won't grow to be too big, and your parents are worried about the puppy's hair shedding all over the furniture. Finding information like this may require a little bit of research, like looking up how big each puppy will grow to be.

Let's say your lists look like this:

Great Dane:

  • Happy puppy
  • Calmer and more relaxed
  • Will grow to be very large
  • Medium shedding
  • Eats a lot
  • Doesn't bark a lot


  • Happy puppy
  • Very energetic and excited
  • Will stay small whole life
  • Very little shedding
  • Eats a little
  • Doesn't bark a lot
