Hi, I am also applying for a new SEN job, but have been teaching SEN for 5 yrs. I would look at doing a sensory story sack and be very interactive. a short story could last 20-25 minutes by the time you go around each pupil. have a look at the b squared skills for pace if you can get hold of a copy. get hold of a big make or switch toy, use symbols if appropriate. hope this helps.
