A Venn diagram shows the relationship between a group of different things. It allows us to sort data into two circles which overlap in the middle.

Venn diagrams are great for helping us organise two sets of things based on their similarities and their differences.

Things that have similarities are shown as overlapping circles, while things that are different stand alone.

For example, if you were to write down the number of children in your class who have brown hair in one circle, and the number of children in your class who wear glasses in another, then in the overlapping circles in the middle you would put down the number of children who have brown hair and wear glasses.

In this video CAL wants to make lots of different soups, but he cannot figure out which ingredients he has and does not have, in order to make the soups he wants.

CAL needs some help!
