This is a 55 page Smartboard file over Set Theory. The 3 topics I'm focusing on are Union, Intersections, and Complements while reading a Venn Diagram. The lesson gives easy to understand definitions along with visuals. There are 2 and 3 circle diagrams. Sometimes students look at the diagram and read it and other times students look at and answer and write the set theory that matches what the graph is showing. There are plenty examples with answers.
