What Is A Venn Diagram: Explained For Primary Parents And Kids

In this post we will be explaining what venn diagrams are, how they can be used and what your child will be learning about them throughout primary school. We’ve also included a number of venn diagram based questions to test your child’s skills, so take a look!

What is a venn diagram?

A Venn diagram (named after mathematician John Venn in 1880) is a method used to sort items into groups.

Venn diagrams explained: How to interpret them

These diagrams are usually presented as two or three circles overlapping, with the overlapping sections containing items that fit into both (or all, if three circles overlap) groups. Items which don’t belong to either/any group are placed on the outside of the circles.

An example of a simple venn diagram:

In the example above, you can see that the words have been sorted into one of four categories: those with 5 letters (placed in the left circle), those with a double consonant (placed in the right circle), those with both 5 letters and a double consonant (placed in the centre overlap) and those with neither (placed round the edge).

Below is another example with three circles creating eight groups.
