An absolutely amazing PowerPoint (created as part of a PGCE assignment). Interactive activities, links and written exercises (these could also be printed as worksheets) plus lots of points for group discussion. Also great for teacher reference / training.
Silent e differentiated worksheets (2 versions) that can be folded so that higher level students can make up their own definitions (or they can be used as a matching exercise).
Plus 2 sets of useful dictation sentences.
