This is a part of a four-lesson bundle on teaching sets or Venn Diagrams with the first two/three applicable for KS4 and the fourth a perfect addition to KS5. There are some elements in lesson three is really geared towards A-Level, but I would teach it to a top set at KS4, but NOT a 2nd set. This lesson comes with an excellent worksheet and a MWB proforma that I use.
All lesson come with additional resources and this is an excellent bundle and is available as a 4 lesson series at a reduced price.
