Relative Clauses [for Speaking Lessons]

The title says it all, this sheet gives a description of relative clauses both defining and non defining, how to form them, use them and shorten them. There is also an idea for a game I play with my students during speaking classes which they all enjoy and actually leads to more conversation / discussion about how difficult (or not) the clues students used were. This also has the more advanced students giving their suggestions for harder/easier or better clues (defining relative clauses) and comparing their ideas.
