A Venn diagram is usually constructed of overlapping circles. Anything inside a circle is a member of that set, anything outside is not a member of the set. Because the circles overlap one thing can be a member of two or more sets. Sounds complex? Well, Venn diagrams used to be introduced much later in the curriculum, but they seem to have crept down to Year 2 now. Not surprisingly, some children find them very difficult to interpret. These pages look at fairly simple examples of Venn diagrams, with just two circles overlapping. Children are asked to put shapes inside the circles, depending on their properties.
